A (10,3)-b net by sulfate hydrogen-bonded biimidazolate complexes

Journal article, 2003

The synthesis and crystal structure of Delta-[Cr(Hbiim)(H(2)biim)(2)]SO4.H2O (H(2)biim = biimidazole) are presented. A network is formed by sligthly distorted Delta-[Cr( Hbiim)(H(2)biim)(2)](2+) octahedra triple bridged by sulfate anions to give a (10,3)-b net. The final structure is given by three such interpenetrating nets, all with the same chirality on chromium. It is shown that the same net and interpenetration occur in [Fe(H(2)biim)(3)]CO3.MeOH.
