摘要：

The title compound, [Ni(dcbp)(H2O)(2)](H(2)dcbp = 2,2'-bipyridine-4,4'-dicarboxyacid), was synthesized under hydrothermal conditions. The structure was determined by single-crystal X-ray diffraction and further characterized by elemental analysis, IR, and TGA. The compound crystallized in an orthorhombic system, P2(1)2(1)2(1) space group, a = 6.7665(7) angstrom, b = 12.9047(14) angstrom, c = 13.1848(15) angstrom, beta = 90 degrees. In the compound, each Ni(II) atom exhibits a six-coordinated distorted octahedral geometry. Interestingly, carboxylate group from dcbp ligands bridges between adjacent Ni(II) atoms giving rise to unprecedented interweaving of hetero-chiral single helical chains into a 3D chiral (10, 3) framework.
