The title polymeric ladder complex, Cu(2)(C(7)H(6)NO(2))(2)(C(10)H(8)N(2))(3)(H(2)O)(2)(2).4H(2)O, has been synthesized and spectroscopically characterized. The polymeric nature of the compound involves two non-equivalent 4,4'-bipyridyl ligands acting as almost orthogonal bridges joining the metal coordination Jahn-Teller-distorted octahedra, and forming ladders packed under the influence of hydrogen bonds involving the uncoordinated amino group of the p-aminobenzoate ligand, the NO(3)(-) anion and the water molecules.
已合成并通过光谱表征了标题聚合物阶梯状配合物，即[Cu₂(C₇H₆NO₂)₂(C₁₀H₈N₂)₃(H₂O)₂₂·4H₂O]ₙ。该化合物的聚合性质涉及两个不等价的4,4'-联吡啶配体，它们作为几乎正交的桥连接金属配位的 Jahn-Teller 畸变八面体，并形成在氢键影响下堆积的阶梯结构，这些氢键涉及对氨基苯甲酸酯配体的未配位氨基、NO₃⁻ 阴离子和水分子。
