The crystal and molecular structure of bis(diphenylphosphino)acetylene

A three-dimensional X-ray diffraction analysis of the structure of bis(diphenylphosphino)acetylene, (C6Hs)2PC=CP(C6Hs)2, has been carried out. The crystals are monoclinic, space group P21/n with a= 14709, b= 8166, c= 17-836 A, p= 95 ° 13', Z= 4. The parameters determined earlier by Brinkel were refined by a block-diagonal least-squares method with 2717 intensities collected with a Hilger-Watts linear diffractometer. The hydrogen atoms were included in the calculations. The final R value, including all reflexions, was 0.061 (R'=0.0064). The molecule has the expected pyramidal configuration about both phosphorus atoms, but in view of the asymmetric orientation of the benzene rings about the P-C bonds, possesses no symmetry, n-Interaction between the phosphorus atoms and the acetylenic group has been advanced to account for the geometry of the molecule. The torsion angle between the directions of the polar axes of the phosphorus lone-pair orbitals is approximately 90 °. Bond lengths and angles do not differ significantly in the two equivalent parts of the molecule. The mean > P-C(Ph) and > P-C = bond lengths are 1.832 and 1.765/~ respectively, and include an angle of 101.1 ° (e.s.d. 0.004/~, and 0-2°). All benzene rings are essentially planar with some significant inand out-of-plane bendings of the exocyclic bonds. The packing arrangement is described.

Crystal and molecular structure of bis[tetracarbonyltriethylphosphinemanganese(0)

Bis[tetracarbonyltriethylphosphinemanganese(0)] crystallises as orange prisms in the space group Aba2 with unit-cell parameters a= 15·94, b= 14·78, and c= 11·60 A. A partial three-dimensional X-ray structural analysis has converged to R= 0·089, and the molecule has been found to bear a striking resemblance to the structure of decacarbonyldimanganese with the carbonyl groups trans to the metal–metal bond replaced by triethylphosphine ligands.

Crystal and molecular structure of bis-(1-m-tolylazo-2-naphtholato)-nickel(II)

The X-ray structural analysis of trans-bis-(1-m-tolylazo-2-naphtholato)nickel(II) has shown that the co-ordination is square-planar, the bonding from the ligand to the metal being through the oxygen atom and the nitrogen atom further from the naphthyl ring. The crystals are monoclinic, P21/c, a= 16·532, b= 5·082, c= 19·382 A, β= 125·04°. Ni–O = 1·85, Ni–N = 1·89 A.

The crystal and molecular structure of bis-(O,O′-diethyldithiophosphato) nickel (II)

The crystal and molecular structure of bis-(O,O′-diethyldithiophosphato) nickel (II), Ni[S 2P(OC 2H 5) 2] 2, has been established by a single crystal three dimensional X-ray study. The monoclinic unit cell, a = 10·48 A ̊ , b = 10·22 A ̊ , c = 8·62 A ̊ , and β = 102·5° has two formula units in the space group P2 1 c . Each nickel atom occupies a centre of symmetry and forms a planar tetracoordinated chelate with the sulphur atoms of two ligand molecules. The disruption of the chelate rings in solvents of high dielectric constant has been attributed to the presence of an ionic nickel-sulphur bond.

The crystal and molecular structure of bis(glyoximato)palladium(II)

Bis(glyoximato)Pd(II), (H 2C 2OOH) 2Pd, crystallizes in the triclinic system with two molecules per unit cell and belongs to space P 1 − . Unit-cell parameters are: a o = 3.5581 Å, b o = 7.7720 Å, c o = 14.0172 Å, α = 89°33′, gb = 91°39′, γ = 89°54′. The structural analysis of this complex, based on all the reflexions accessible with Cu K α radiation and measured by an automatic diffractometer (final R value 0.046), shows that in the two crystallographically non equivalent molecules Pd atoms coordinate four N atoms on a plane and that the whole molecules are planar. The intramolecular hydrogen bonds O-H- - -O, have to be considered asymmetric. Pd atoms are not interested in any contact, while some intermolecular contacts between C and O atoms are worth recording.

The crystal and molecular structure ofbis(hydrazine)zincbis(hydrazincarboxylate-N′,O)

The crystal and molecular structure of bis (hydrazine)zinc bis (hydrazincarboxylate-N′,O), Zn(N 2 H 4 ) 2 (H 2 N′–NH · COO) 2 , has been determined. The crystal structure consists of single molecules bound to one another by hydrogen bonds. Each molecule is an octahedral chelate. The six corners of the coordination octahedron are occupied by two nitrogen atoms belonging to two hydrazine molecules and by two nitrogen atoms and two oxygen atoms, all belonging to two hydrazincarboxylic groups. The bond distances between zinc and surrounding atoms are: Zn–O = 2.05 Å, Zn–N = 2.25 Å and 2.17 Å. The distances between nitrogen atoms, in hydrazinic groups, are: N–N = 1.46 Å, for the hydrazine molecule, and 1.39 Å, for the hydrazinic group of the acid. In the group–NH · COO − the atoms C, N and both O lie in the same plane. The distances C–O = 1.30 Å and 1.25 Å correspond to those found in carboxylic acids and carboxylates.
