4,4'-Dimethoxy-2,2'-[1,1'-(propane-1,3-diyldinitrilo)diethylidyne]diphenol.

ABSTRACT: In the crystal structure, the title Schiff base compound, C(21)H(26)N(2)O(4), has twofold rotation symmetry. The imino group is coplanar with the aromatic ring. An intra-molecular O-H?N hydrogen bond forms a six- membered ring, producing an S(6) ring motif. The two benzene rings are almost perpendicular to each other, making a dihedral angle of 85.00?(2)°. The meth-oxy group is approximately coplanar with the benzene ring, with a C-O-C-C torsion angle of 2.34?(12)°. Neighbouring mol-ecules are linked together by weak inter-molecular C-H?O hydrogen bonds and a C-H?? inter-action, forming a sheet parallel to the ab plane. The mol-ecules also adopt a zigzag arrangement along the c axis.
