摘要：

Two metal complexes of 1,4,7-triazacyclodecane (tacd), [Zn(tacd)(2)](ClO4)(2) (1) and [Cu(tacd)(2)]Br-2.4H(2)O (2), have been prepared and characterized by X-ray crystallography. Crystals of (1) are monoclinic, P2(1)/n, a 9.506(2), b 10.279(3), c 11.505(2) Angstrom, beta 91.29(2)degrees; crystals of (2) are orthorhombic, Pbca, a 12.035(3), b 13.673(3), c 14.248(2) Angstrom. The zinc(II) atom in (1) is surrounded in a distorted octahedral N-6 environment with Zn-N bonds at 2.121(5)-2.131(4) Angstrom; the copper(II) atom in (2) adopts an elongated octahedral coordination geometry with the Cu-N bonds at 2.066(4)-2.294(5) Angstrom.
