In the title salt, [Co(C(5)H(4)N(2)O(2))(2)(H(2)O)(2)]Cl(2), the Co(II) ion is located on an inversion center. It is chelated by two neutral pyrimidine-2-carboxylic acid molecules and is coordinated by two water mol-ecules in an octa-hedral coordination geometry. The cations and anions are linked via O-H⋯Cl hydrogen bonds into a layer structure; an intra-molecular O-H⋯N hydrogen bond connects the carboxylic acid group to the pyrimidine N atom.
在标题盐[Co(C₅H₄N₂O₂)₂(H₂O)₂]Cl₂中，Co(II)离子位于一个对称中心上。它由两个中性的嘧啶-2-羧酸分子螯合，并通过两个水分子以八面体配位几何构型配位。阳离子和阴离子通过O—H⋯Cl氢键连接成层状结构；分子内的O—H⋯N氢键将羧酸基团与嘧啶N原子相连。
