Deskripsi
In the centrosymmetric binuclear title molecule, [Co2(SO4)2(C8H7N3)4], the CoII ion is coordinated by two N,N′-bidentate 3-(2-pyridyl)pyrazole ligands and two sulfate ions, generating a distorted cis-CoO2N4 octahedral 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 intramolecular N—H...O hydrogen bonds help to establish the molecular conformation.
