Di-μ-sulfato-κ4 O:O′-bis[diaqua(1H-imidazo[4,5-f][1,10]phenanthroline-κ2 N 7,N 9)cobalt(II)] dihydrate

In the centrosymmetric dinuclear title compound, [Co2(SO4)2(C13H8N4)2(H2O)4]·2H2O, the CoII atom is coordinated by two N atoms from two 1H-imidazo[4,5-f][1,10]phenanthroline ligands, two O atoms from two sulfate anions and two O atoms from water molecules in a distorted octahedral geometry. The Co⋯Co separation is 5.1167 (7) Å. The coordinated and uncoordinated water molecules engage in N—H⋯O and O—H⋯O hydrogen-bonding interactions.
