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

ABSTRACT: In the title compound, [Ni(2)Cl(2)(C(20)H(18)N(4))(H(2)O)(4)]Cl(2)·2C(2)H(6)O, the coordination environment of each Ni(2+) ion is distorted octa-hedral formed by two N atoms from the Schiff base ligand, two O atoms from water mol-ecules and two chloride anions acting as ?(2) bridges between the metal ions. The coordinated water mol-ecules are linked to the uncoordinated ethanol mol-ecules and chloride anions by O-H?O and O-H?Cl hydrogen bonds, although the assignment of some of these is tentative. A weak inter-molecular O-H?N inter-action within the ligand is also observed.
