title: 5,5'-Bis(diethyl-amino)-2,2'-[2,2-di-methyl-propane-1,3-diylbis-(nitrilo-methylidyne)]diphenol.
abstract: The asymmetric unit of the title compound, C(27)H(40)N(4)O(2), comprises one mol-ecule of a potentially tetra-dentate Schiff base ligand. The dihedral angle between the two phenyl rings is 67.13 (10)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. One terminal methyl among the four diethyl-amino groups is disordered over two positions with the refined site occupancy ratio of 0.660 (7)/0.340 (7).
