The reaction of Co(NO(3))(2)·3H(2)O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C(7)H(3)NO(4))(C(5)H(8)N(2))(3)]·H(2)O. The Co(II) atom is coordinated by one pyridine-2,6-dicarboxyl-ate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octa-hedral geometry. Hydrogen-bonding interactions involving the coordinated carboxylate group, 3,5-dimethyl-1H-pyrazole and water help to consolidate the crystal structure.
硝酸钴(II)三水合物与吡啶 - 2,6 - 二羧酸和3,5 - 二甲基 - 1H - 吡唑按1:1:3的摩尔比反应,得到标题配合物[Co(C₇H₃NO₄)(C₅H₈N₂)₃]·H₂O。钴(II)原子由一个吡啶 - 2,6 - 二羧酸根螯合配体和三个3,5 - 二甲基 - 1H - 吡唑配体以扭曲的八面体几何构型配位。涉及配位羧酸根基团、3,5 - 二甲基 - 1H - 吡唑和水的氢键相互作用有助于巩固晶体结构。
