Playing with [{Mo6Bri6Sei2}(CN)a6]4− Cluster Building Blocks and Mn(salen)+ Nodes for the Crystal Engineering of Inorganic Coordination Polymers

Abstract

AbstractWe present here the syntheses and structural characterizations of inorganic polymeric cluster compounds, Cs[Mn(salen)]3[{Mo6Br6Se2}(CN)6] (1) and (H3O)(TBA)[Mn(salen)]2[{Mo6Br6Se2}(CN)6] (2) (TBA=tetrabutylammonium ((n‐C4H9)4N+)), built‐up from [{Mo6Br6Se2}(CN)6]4− molecular building blocks and Mn(salen)+ complexes (salen = salen = N,N′‐bis(salicylidene)ethylenediamine). The nature of additional counter cations (i. e. Cs+ or TBA+) enables to control the interactions between the [{Mo6Br6Se2}(CN)6]4− building blocks and the Mn(salen)+ groups. Thus, 1 was obtained by slow diffusion of a methanol solution of K2Cs2[{Mo6Br6Se2}(CN)6] cluster compound into a methanol solution of Mn(salen)ClO4. 2 was obtained in a similar way but after the addition of tetrabutylammonium bromide into the solution of Mn(salen)ClO4. 1 is a bimetallic 3D coordination compound ( ) and 2 is a bimetallic 2D compound ( ). Structural correlations between 1 and 2 are discussed and compared with relevant examples found in the literature.
