{μ-N,N′-Bis[1-(2-pyridyl)ethylidene]benzene-1,2-diamine}di-μ-chlorido-bis[diaquanickel(II)] dichloride ethanol disolvate

Abstract

In the title compound, [Ni2Cl2(C20H18N4)(H2O)4]Cl2·2C2H6O, the coordination environment of each Ni2+ ion is distorted octahedral formed by two N atoms from the Schiff base ligand, two O atoms from water molecules and two chloride anions acting as μ2 bridges between the metal ions. The coordinated water molecules are linked to the uncoordinated ethanol molecules and chloride anions by O—H...O and O—H...Cl hydrogen bonds, although the assignment of some of these is tentative. A weak intermolecular O—H...N interaction within the ligand is also observed.
