Bis({1-[(1-imino­eth­yl)imino]­eth­yl}aza­nido-κ²N¹,N⁵)nickel(II) methanol monosolvate

The title compound, [Ni(C₄H₈N₃)₂]·CH₃OH, contains two independent Ni^II atoms, each located on an inversion center and coordinated by four N atoms from two 1-[(1-imino­eth­yl)imino]­eth­yl}aza­nide ligands in a square-planar geometry. N—H...N, N—H...O and O—H...N hydrogen bonds link the complex mol­ecules and methanol solvent mol­ecules into a corrugated layer parallel to (001).
