Preparation of nanoporous molecular based-solid produced by tris-2,2'-biimidazolate CoIII complexes

Abstract The [CoIII(Hbim)3] (1) (Hbim = 2,2′-biimidazolate monoanion) is synthesized and its crystal structure is characterized by X-ray crystal analysis. (Crystal data: monoclinic, C2/m (No. 12), FW = 970.71, a = 17.144(5) A, b = 30.341(6) A, c = 16.422(5) A, β = 104.38(2)°, V = 8274(3) A3,Z = 8) The crystal structure comprises assemblies of two-dimensional honeycomb sheet structures built up by alternate arrangements of Δ and Δ binary optical isomers of the building block 1 The two-dimensional sheets are formed by complementary intermolecular hydrogen bonds of Hbim− ligands containing the building block 1. Interestingly, two-dimensional sheets is stacked along c axis to form the microporous crystal with large channels.
