摘要:
                                The title compound, [Cu(C2N3)(C3H10N2)(2)] ClO4, is made up of [Cu(tn)(2){N(CN)(2)}](+) complex cations (tn is 1,3-diaminopropane) and ClO4- anions. The Cu-II atom is coordinated by four N atoms of two equatorial tn ligands, with an average distance of 2.041 (7) angstrom, and one nitrile N atom of the dicyanamide anion in an axial position, at a distance of 2.236 (3) angstrom, in a manner approaching square-planar coordination geometry. The complex has C-s symmetry, with the mirror plane lying through the central C atoms of both tn ligands and the dca ligand. The ClO4- anion might be considered as very weakly coordinated in the opposite axial position [ Cu - O = 2.705 ( 3) angstrom], thus completing the Cu-II coordination to asymmetric elongated octahedral (4+1+ 1*). The Cu atom and the perchlorate anion both lie on mirror planes.
