摘要

A novel cobalt complex [Co(2,5-PDC)(2)(H2O)(2)Co(H2O)(4)](.)4H(2)O (2,5-PDCH2 = 2,5-pyridinedicarboxylic acid) was synthesized and its crystal structure has been determined by X-ray diffraction. The crystallographic data are: triclinic P-1, a = 7.112(2) angstrom, b = 8.939(3) angstrom, c = 9.719(3) angstrom, alpha = 91.153(5)degrees, beta = 101.136(5)degrees, gamma = 108.001(4)degrees, V = 574.4(3) angstrom(3), Z = 1. The compound [Co(2,5-PDC)(2)(H2O)(2)Co(H2O)(4)](.)4H(2)O exhibits a novel one-dimensional network constructed from the interconnection of Co(2,5-PDC)(2)(H2O)(2) and Co(H2O)(4), in which two kinds of six-coordinated Co(II) atoms have both octahedral coordination environments. Each 2,5-PDC anion connects two different coordinated cobalt ions alternately in an one-dimensional chain. The zigzag 1D alternating chains are linked by extensive hydrogen bonds to form a three-dimensional (3D) supramolecular structure, in which uncoordinated solvate molecules act as space filling particles.
