Abstract

The first example of polyoxovanadate layered framework with a cobalt coordination complex as a pillaring unit, CoII(mu-C2N2H8)(2)[(V4V2O14)-V-IV-O-V], was readily synthesized under hydrothermal conditions. The structure can be solved and refined in monoclinic P2(1)/n with a = 9.143(3) angstrom, b = 6.5034(11) angstrom, c = 15.874(4) angstrom, beta = 101.90(2), V = 923.6(4) angstrom(3) and Z = 2. The crystal structure comprises two-dimensional (V4V2O14)-V-IV-O-V}(2-) layers extending parallel to [101], constructed from tetrahedral {(VO4)-O-V} and square pyramidal {(VO5)-O-IV} building units. Adjacent layers are linked through the octahedral {(CoO2)-O-II(mu-C2N2H8)(2)} pillars, within which the CoII resides on an inversion center. The structure displays N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonding between the ethylenediamine and vanadium oxide layers.
