(Dicyanamido)[tris(2-pyridylmethyl)amine]zinc(II) perchlorate

H. Li, H. Y. Zhao and S. G. Zhang

Abstract: In the title complex, [Zn(C₂N₃)(C₁₈H₁₈N₄)]ClO₄, the Zn^II ion has a slightly distorted trigonal-bipyramidal ZnN₅ coordination geometry. The crystal structure is stabilized by weak intermolecular C-HO and C-HN hydrogen bonds. In addition, there are relatively close contacts between the O atoms of the perchlorate anion and symmetry-related pyridine rings [OCg = 3.179 (3) and 3.236 (3) Å, where Cg is the centroid of a pyridine ring], and between the terminal N atom of the dicyanamide ligand and pyridine rings [NCg = 3.381 (4)-3.761 (3) Å]. The central N atom of the dicyanamide ligand is disordered over two sites in an approximately 0.6:0.4 ratio.
