2-[(1,3-Benzo-thia-zol-2-yl)imino-meth-yl]-6-meth-oxy-phenol: a new monoclinic polymorph.

ABSTRACT: The title compound, C15H12N2O2S, is a P21/c polymorph of a previously reported P21/n polymorph [Büyükgüngör et al. (2004 ?). Acta Cryst. E60, o1414-o1416]. The dihedral angle between the benzo-thia-zole (r.m.s. deviation = 0.010?Å) and the benzene ring of 7.86?(6)° compares with 10.76?(10)° in the literature structure. The meth-oxy substituent is almost coplanar with the benzene ring to which it is attached [C-O-C-C torsion angle = 178.31?(14)°] and the conformation about the imine bond [1.287?(2)?Å] is E. There is an intra-molecular O-H?N hydrogen bond and the hy-droxy O and thio-ether S atoms are syn. In the crystal, columns are formed along the b axis as centrosymmetric dimeric aggregates, mediated by C-H?O inter-actions and linked by ?-? inter-actions between the thia-zole and benzene rings [centroid-to-centroid distance = 3.8256?(10)?Å].
