In the centrosymmetric title compound, [Co2(C12H10O2P)4(C5H5N)4(H2O)2], each approximately octahedral Co atom features two trans-coordinated pyridine molecules, one water molecule, a terminally coordinated monodentate diphenylphosphinate ligand, and two bidentate diphenylphosphinate ligands that bridge the two Co atoms across a centre of inversion to form a dimeric binuclear complex. The discrete molecules are linked by double hydrogen bonds between the terminally coordinated diphenylphosphinate ligand and the water molecule to form a continuous chain along the crystallographic b axis.
