The title compound, Co(C(12)H(6)N(2)O(4))(H(2)O)(2), has been hydrothermally synthesized and structurally characterized. It consists of polymeric chains of [Co(mu-(2,2'-bipyridyl-3,3'-dicarboxylato-kappa(4)N,N':O,O'))(H(2)O)(2)] units, in which each Co(II) cation is octahedrally coordinated by two chelating pyridyl N atoms, two chelating carboxyl O atoms from different carboxylate groups of another bipyridyl ligand, and two water molecules as terminal ligands. A crystallographic twofold axis parallel to the chain axis, passes through the Co atom.
标题化合物[Co(C₁₂H₆N₂O₄)(H₂O)₂]ₙ通过水热法合成并进行了结构表征。它由[Co(μ-(2,2'-联吡啶-3,3'-二羧酸根-κ⁴N,N':O,O'))(H₂O)₂]单元的聚合物链组成,其中每个Co(II)阳离子由两个螯合的吡啶基N原子、来自另一个联吡啶配体不同羧酸根基团的两个螯合羧基O原子以及两个作为端基配体的水分子八面体配位。一条平行于链轴的晶体学二重轴穿过Co原子。
