Aqua-1kappaO-{micro-1,3-bis[2-(2-oxidobenzylideneamino)ethyl]-2-(2-oxidophenyl)imidazolidine-1kappa4O,N,N',O';-2kappa4O',N'',N''',O''}(micro-2-formylphenolato-1:2kappa3O1:O1,O2)-dinickel(II) trihydrate: a one-dimensional chain linked by O-H...O hydrogen bonds and C-H...pi interactions.
In the title compound, [Ni(2)(C(7)H(5)O(2))(C(27)H(27)N(4)O(2))(H(2)O)].-2.38H(2)O, each Ni atom is coordinated by two N atoms and four O atoms from the heptadentate Schiff base ligand and one salicylaldehyde or water molecule, forming an asymmetric molecule with three bridges linking the two Ni(II) ions, which are separated by 3.081 (1) A. Hydrogen-bonded water and C-H...pi interactions take part in the stabilization of the complex. The complex molecules are connected into a one-dimensional chain along the c axis by O-H...O hydrogen bonds between coordinated and solvent water molecules and by C-H...pi interactions.
