Kristallstrukturen zweier Kupfer(II)-Cyclam-Komplexe: [{CuCl(C10N4H24)}2][CdCl4] und [Cu(C10N4H24)][CdCl3(H2O)2]Cl

Pickardt, Joachim; Hoffmeister, Isabella

Crystals of both complexes were obtained by evaporation of the ethanol solvent. The crystals of [{CuCl(C10N4H24)}2][CdCl4] are tetragonal, space group I4̄2d, Z = 4, a = b = 1784.1(11), c = 1101.1(8) pm. Each copper atom is bonded to one cyclam ligand and two chlorine atoms which are acting as bridging ligands and connect the copper atoms to chains of distorted octahedra. Distorted tetrahedra of CdCl4 are situated in cavities between these chains. The crystals of [Cu(C10N4H24)][CdCl3(H2O)2]Cl are monoclinic (b), space group C2/c, Z = 4, a = 1581.9(8), b = 1323.3(7), c = 924.0(5) pm, β = 94.31(5)°. Cadmium is coordinated to four chlorine atoms and two water molecules, while all of the chlorine atoms act as bridging ligands connecting every cadmium atom to two adjacent cadmium atoms and to two copper atoms which lie in plane with the N atoms.
