One naphthalene-1,4-dicarboxylate dianion in the title compound, [Cu2(C12H6O4)2(C14H8N4)2]·4H2O, bridges two N-heterocycle-chelated Cu atoms whereas the other one bridges four N-heterocycle-chelated Cu atoms, linking them into a flat carboxylate-bridged layer. The two independent Cu atoms show square-pyramidal coordination. Water molecules occupy the space between adjacent layers; they are possibly disordered, and their H atoms were not located.

The title compound, C31H39NO, was prepared by the condensation of 5- tert-butyl-2-hydroxy-3-(1-phenylethyl)benzaldehyde with 2,6-diisopropylphenylamine in refluxing ethanol. The phenol ring and the phenylimino ring are approximately perpendicular, forming a dihedral angle of 81.5 (3)°. The phenyl ring makes a dihedral angle of 75.2 (2)° with the phenol ring and also makes a dihedral angle of 62.9 (3)° with the phenylimino ring. The molecular structure is stabilized by an intramolecular O—H...N hydrogen bond linking the phenol OH group and the phenylimino N atom. One of the isopropyl groups is disordered over two positions; the site occupancies are 0.55 and 0.45. [ABSTRACT FROM AUTHOR]
