✦ Synopsis

In the title compound, [Co(C~10~H~7~NO~2~)~2~(H~2~O)~2~], the Co^II^ ion lies on an inversion centre. It has a distorted octahedral geometry and is coordinated by two N,O-bidentate 5-phenyl-1__H__-pyrazole-3-carboxylate ligands and two water molecules. Intermolecular O—H...O and N—H...O hydrogen bonds link molecules into layers parallel to the (010) plane.
