Abstract:  The cobalt(II) cations in cobalt(II) tetrahydrogentris(orthophosphite) CoH₄(HP0₃)₃ • 2H₂O are surrounded in the rather labile coordination sphere with the shape of a distorted octahedron by the oxygen atoms from two phosphite groups and two water molecules. An important role in the coordination sphere is played by hydrogen bonding between the water molecules themselves, between the water molecules and the anion with a bond length 0.281—0.305 nm, and in the [H₄(HP0₃)₃]^2- anion itself with a bond length 0.257—0.265 nm.
