4,4'-Dimethyl-2,2'-[(3-aza-pentane-1,5-di-yl)bis-(nitrilo-methyl-idyne)]diphenol.

In the crystal structure of the title Schiff base, C(20)H(25)N(3)O(2), the salicylaldimine groups at each end of the mol-ecule are essentially planar and make a dihedral angle of 84.94 (3)° with each other. There are strong intra-molecular O-H⋯N hydrogen bonds and a weak inter-molecular N-H⋯O hydrogen bond.

Bis{2-[(E)-benzyl-imino-meth-yl]-4-methyl-phen-olato-κN,O}cobalt(II).

In the title complex, [Co(C(15)H(14)NO)(2)], the Co(II) atom, situated on an inversion centre, is coordinated by two O and two N atoms from two symmetry-related bidentate Schiff base ligands in a slightly distorted square-planar geometry. The two phenolate rings form a dihedral angle of 10.53 (2)°.
