Synthesis and structural characterization of 0D vanadium borophosphate [Co(en)(3)](2)[V(3)P(3)BO(19)][H(2)PO(4)].4H(2)O and 1D vanadium oxides [Co(en)(3)][V(3)O(9)].H(2)O and [Co(dien)(2)][V(3)O(9)].H(2)O templated by cobalt complexes: cooperative organization of the complexes and the inorganic networks.
A 0D vanadium borophosphate [Co(en)(3)](2)[V(3)P(3)BO(19)][H(2)PO(4)].4H(2)O (1) and two 1D vanadium oxides [Co(en)(3)][V(3)O(9)].H(2)O (2) and [Co(dien)(2)][V(3)O(9)].H(2)O (3) have been synthesized hydrothermally from the reaction mixture of V(2)O(5)-H(3)PO(4)-H(3)BO(3)-CoCl(2)-R-H(2)O at 110 degrees C (R: en or dien). The complex cations Co(en)(3)(3+) and Co(dien)(2)(3+) are cooperatively organized in the reaction medium to play a structure-directing role in the formation of the inorganic clusters and chains. The structures are determined by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction, ICP, and TG analyses. The structure of 1 contains isolated [V(3)P(3)BO(19)](5)(-) cluster anions, H(2)PO(4)(-) anions, racemic Co(en)(3)(3+) cations, and H(2)O molecules, which form a complex H-bond network. 2 and 3 both contain chains of corner-sharing VO(4) tetrahedra running along the 2(1) screw axis. The complex cations located in the interchain region interact with the chains through H-bonds. 2 is crystallized in an enantiomorphic space group and only one enantiomer of Co(en)(3)(3+) is involved in the structure.
