The compounds have the formula [M(C7H3O2Cl2)2x4H2O], were M=Co(II), Ni(II) and their crystals are isomorphous in the monoclinic space group P2(1)/c with a=10.151(3) A, b=6.221(2) A, c=29.636(6) A and beta=93.51(3)degree for the Co(II) complex and a=10.063(3) A, b=6.200(2) A, c=29.820(6) A and beta=93.40(3)degree for the Ni(II) complex. The structure were solved by the heavy-atom method and refined to the final R=0.0293, wR=0.075 for 3150 observed reflections for the Co(II) complex and R=0.0487 and wR=0.116 for 2545 observed reflections for the Ni(II) complex. The metal(II) ion is coordinated by two oxygen atoms of two monodentate czrboxylate groups of 3,4-dichlorobenzoate anions and four oxygen atoms from water molecules. The M-O distances range from 2.050(2) A to 2.148(2) A for the Co(II) complex and from 2.039(3) A to 2.111(3) A for the Ni(II) complex.
