Energetics of organic solid-state reactions: the topochemical principle and the mechanism of the oligomerization of the 2,5-distyrylpyrazine molecular crystal

The 30-fold difference in reactivity of the isomorphous crystals of 2,5-distyrylpyrazine (DSP) and 1,4-bis-(3-pyridyl-2-vinyl)benzene (P2VB), two isoelectronic and nearly structurally identical molecules, has remained an important problem in organic solid-state chemistry. This disparity of oligomerization rates in the solid state is further accentuated by the fact they have similar rates of reaction in solution. The differences in reactivity of these molecular crystals cannot be explained from topochemical considerations. To more completely understand the discrepancy of reactivity of these archetypical photochemical solid-state reactions, the oligomerization of DSP has been reexamined

A Simple Way to Predict the Products of Topochemical Photoreactions on the Basis of Force Field Calculations

Not only topochemically allowed, but also the topochemically forbidden products that are partly formed on the photodimerization of crystalline butenolides 1 can be qualitatively correctly predicted with the modified Cohen model presented here. Thus the way is clear for the application of standardized molecular-modeling procedures to problems in organic solid state chemistry.

The Growth of Organic Solid State Chemistry: A Personal Perspective

Abstract Some aspects of the development of organic solid state chemistry are described from the point of view of one of the participants.

A Modelling Approach to Organic Solid-State Chemistry

Abstract A method is described for the analysis of non-bonded forces in crystalline organic compounds. It is developed by reference to the photoreactive compound 2-benzyl-5-benzylidene-cyclopentanone (BBCP) and its derivatives, but it is of general validity. The approach is valuable for predicting the structural consequences of substitution at different positions in a given molecule; this ability is of importance in predicting the reactivity of organic solids.

The suggested role of partial dislocations in the single crystal ? single crystal phase transition of a cyclo-octane molecular cationic salt

It is suggested that the facile low-temperature solid-state inter-conversion of the α- and β-phases of 5-methyl-1-thia-5-azoniacyclo-octane 1-oxide perchlorate occurs on recurrent (102) type planes. The mechanism, which is likely to be of general validity in organic solid-state chemistry, dispenses with the need to postulate co-operative conformational changes on half of the molecular cations (mol-ions) in each row and in each column, and also explains all the known experimental facts relating to the transition.

Topography and topology in solid-state chemistry

A survey of recent activity and current trends in solid-state chemistry reveals that several novel and seemingly unrelated physicochemical phenomena, together with some bio-organic, mineralogical and metallurgical attributes of the solid-state, can now be interconnected. Four main topics are discussed. First, so far as the behavioural patterns of organic solids are concerned, topochemical control is often crucial, and it transpires that the reactivity of many types of unsaturated molecules is governed more by the precise molecular orientation and stacking sequences within the crystal structure than by the intrinsic electronic properties of the molecule itself. This fact has led to the synthesis, by the strategem of ‘crystal engineering’ (Schmidt 1971), of stereochemically-pure, organic products and also of single-crystal, extended-chain polymers both of which are difficult if not impossible to prepare by conventional (solution) techniques. It has also led to absolute asymmetric syntheses, under abiotic conditions, from optically inactive materials, by inducing solid-state or surface reactions in chiral crystals. The selectivity and high yields of gas reactions with organic solids, and the facile conversion of polymer crystals from their folded-chain to extended-chain forms are other manifestations of topochemical control in organic solid-state chemistry. Structural defects, too, can play a dominant role, and they account for the not infrequent production of topochemically ‘forbidden’ molecules in photo-induced reactions. The existence of stress-induced and photo-induced phase transformations and of structure-mimicry (in which guest species assume the molecular structure of the host) are further recent discoveries in this general area. Second, topochemical control, which needs to be distinguished from topotaxy, is often important in the reactions of inorganic solids, particularly in intercalation (or its reverse) in which charged or neutral guest species are accommodated between the individual sheets of layered compounds, thereby resulting in expansion of the interlayer separation distances and, generally, some modification of the stacking sequence. Exceptionally selective organic reactions may be carried out in the interlamellar spaces of silicate minerals, and crystal engineering, in the sense that reactant molecules are locked in well defined orientations conducive for subsequent reaction within inorganic matrixes, again becomes a feasible proposition. The third topic of discussion is stacking sequences and stacking faults, which serve as the nexus between the chemistry of layered solids and the structural principles of inorganic solids in general. The relations between the structural characteristics of a range of inorganic solids, and plausible mechanisms of interconversion based on martensitic transformation, follows logically; and changes of coordination number (in going from NaC1- to CsC1-type structures for example) may be rationalized in terms of continuous topological variation. Stacking faults are intimately connected both with partial dislocations and antiphase boundaries, and these, in turn, figure as important concepts in the understanding of the ultramicrostructure of grossly non-stoicheiometric solids, which is the main theme for the fourth topic discussed here. The chemical consequences of linear and planar faults are surveyed, there being a summarizing account of their role in the reactivity of solids, and a fuller one of single, double and pivoting crystallographic shear planes. Relations between shear and block structures are adumbrated; and the merit of introducing the notion of cylindrical fault boundaries, so as inter alia to relate ReO 3 -type to tungsten bronze structures, is outlined. The considerable analogical value of dislocation theory in interpreting the ultramicrostructural characteristics of non-metallic solids, especially as revealed by electron microscopy, is emphasized throughout.
