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 benzothiazole (r.m.s. deviation = 0.010 Å) and the benzene

The distorted octahedral geometry about the SnIV atom in the title compound, [Sn(C6H5)2(C14H19N4S)Cl], is defined by the N,N,S-tridentate Schiff base ligand, two mutually trans ipso-C atoms of the Sn-bound phenyl groups, and the Cl atom which is tran

Two independent diphenyltin molecules and two independent methanol molecules comprise the asymmetric unit of the title compound, [Sn(C6H5)2(C17H14N2O3)]·CH3OH. The Sn atom in each is five-coordinated by a tridentate ligand and the ipso-C atoms of th

In the title thiourea derivative, C16H17N3OS, the hydroxy- and methyl-substituted benzene rings form dihedral angles of 9.62 (12) and 55.69 (6)°, respectively, with the central CN3S chromophore (r.m.s. deviation = 0.0117 Å). An intramolecular O—H

In the title thiourea derivative, C10H17N3O2S, the carboxyl group and the least-squares plane through the cyclohexyl ring are twisted out of the plane through the central CN3S residue; the respective dihedral angles are 7.18 (8) and 62.29 (4)°. The
