Bis[N-ethyl-N'-(pyridin-2-ylmethylene)ethane-1,2-diamine]nickel(II) bis(perchlorate)

Z. Hong

Abstract: The asymmetric unit of the title compound, [Ni(C₁₀H₁₅N₃)₂](ClO₄)₂, consists of 1.5 mononuclear nickel(II) complex cations, two perchlorate anions and two half-perchlorate anions. One of the complex cations and two of the perchlorate anions possess crystallographic twofold rotation symmetry. The Ni atom is coordinated by six N atoms from two N-ethyl-N'-(pyridin-2-ylmethylene)ethane-1,2-diamine ligands in a slightly distorted octahedral geometry. All chemically equivalent bond lengths and angles in the two complex molecules are comparable with each other. Each ligand adopts an approximately planar geometry, except for the terminal ethyl groups. The crystal structure involves intermolecular N-HO hydrogen bonds.
