 Abstract    etallkom plexe m it C yanoguanidin als L iganden: K ristallstru k tu ren von [Cd(cnge)2F2]*3H20 , C d(cnge)2B r2 und Hg(cnge)Cl2 (enge = C yanoguanidin) M etal C om plexes with C yanoguanidine as Ligand: Crystal Structures o f [Cd(cnge)2F2]-3H 20 , C d(cnge)2 Br^ and H g(cnge)C l2 (cnge = Cyanoguanidine) Crystals of [Cd(cnge)2F2]-3H20 (1), Cd(cnge): Br2 (2) and Hg(cnge)Cl2 (3) (cnge = cya­ noguanidine) 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, 3 = 101.05(2)°; 2 is monoclinic, space group P2,/n, Z = 2 , a = 3 9 1.9(I), b = 850.7(2), c = 1722.1(4) pm, ß = 94.06(2)°, 3 is triclinic, space group P I, Z = 1, a = 686.7(1), b = 693.0(5), c = 387.2(4) pm, a = 94.45(5)°, ß = 95.05(4)°, 7 = 78.58(5)°. In 1 and 2 each Cd atom is bonded to four halogen atoms to form polymeric (CdF2)" and (CdBr2)" chains, resp., and to two cyanoguanidine molecules. In 3 each Hg atom is bonded to four chlorine atoms also forming (HgCl2)" chains, which are connected via cyanoguanidine molecules acting as a bidentate bridging ligands to form a network.
