In the centrosymmetric binuclear title molecule, [Co(2)(SO(4))(2)(C(8)H(7)N(3))(4)], the Co(II) ion is coordinated by two N,N'-bidentate 3-(2-pyrid-yl)pyrazole ligands and two sulfate ions, generating a distorted cis-CoO(2)N(4) octa-hedral geometry for the metal atom. The dihedral angles between the pyridine and pyrazole rings in the two ligands are 10.5 (2) and 7.38 (19)°. The bridging sulfate ions generate an eight-membered ring and intra-molecular N-H⋯O hydrogen bonds help to establish the mol-ecular conformation.
在中心对称的双核标题分子[Co₂(SO₄)₂(C₈H₇N₃)₄]中，Co(II)离子由两个N,N'-双齿的3-(2-吡啶基)吡唑配体和两个硫酸根离子配位，为金属原子生成了一个扭曲的顺式CoO₂N₄八面体几何构型。两个配体中吡啶环和吡唑环之间的二面角分别为10.5 (2)°和7.38 (19)°。桥连的硫酸根离子形成一个八元环，分子内的N-H⋯O氢键有助于确定分子构象。
