Two metal complexes of 1,4,7-triazacyclodecane ( tacd ), [Zn( tacd )2] (ClO4)2 (1) and [Cu( tacd )2] Br2.4H2O (2), have been prepared and characterized by X-ray crystallography. Crystals of (1) are monoclinic, P21/n, a 9.506(2), b 10.279(3), c 11.505(2) Ǻ, β 91.29(2)°; crystals of (2) are orthorhombic, Pbca, a 12.035(3), b 13.673(3), c 14.248(2) Ǻ. The zinc(II) atom in (1) is surrounded in a distorted octahedral N6 environment with Zn-N bonds at 2.121(5)-2.131(4) Ǻ; the copper(II) atom in (2) adopts an elongated octahedral coordination geometry with the Cu-N bonds at 2.066(4)-2.294(5) Ǻ.
