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

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 octa­hedral formed by two N atoms from the Schiff base ligand, two O atoms from water mol­ecules and two chloride anions acting as μ(2) 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.
