Abstract: Crystals of [Cd(cnge)2F2]·3H2O (1), Cd(cnge)2Br2 (2) and Hg(cnge)Cl2 (3) (cnge = cyanoguanidine) were obtained by crystallisation from solutions of CdF2, CdBr2 or HgCl2 and cyanoguanidine in water/ethanol or methanol. 1 crystallizes monoclinically, space group C2, Z = 2,a = 1629.2(4), b = 1056.6(4), c = 353.9( 1) pm, β = 101.05(2)°; 2 is monoclinic, space group P21/n, Z = 2, a = 391.9(1), b = 850.7(2), c = 1722.1(4) pm, β = 94.06(2)°, 3 is triclinic, space group P1, Z = 1, a = 686.7( 1), b = 693.0(5), c = 387.2(4) pm, α = 94.45(5)°, β = 95.05(4)°, γ = 78.58(5)°. In 1 and 2 each Cd atom is bonded to four halogen atoms to form polymeric (CdF2)n and (CdBr2)n chains, resp., and to two cyanoguanidine molecules. In 3 each Hg atom is bonded to four chlorine atoms also forming (HgCl2)n chains, which are connected via cyanoguanidine molecules acting as a bidentate bridging ligands to form a network.
