The crystal and molecular structure of N-(4-chloro)benzoyl-N'-2-tolylthiourea (C(15)H(13)N(2)OSCl, M(r) = 304.79) is determined by X-ray diffraction. The crystal structure is monoclinic, space group P2(1)/n with a = 3.9898(3), b = 22.922(2), c = 16.005(2) Angstrom, beta = 104.367(4)degrees, V = 104.367(4) Angstrom(3), Z = 4, D(c) = 1.428 g/cm(3). The results of extended MO calculations using density functional theory (DFT) with a hybrid B3LYP density functional approximation and FTIR and NMR studies on the title compound are reported. With the basis sets of the 6-311G* quality, the DFT calculated bond parameters, harmonic vibrations and chemical shifts are in a very good agreement with experimental data. The intramolecular and intermolecular hydrogen bonds are discussed. Non-linear optical properties of the molecule are predicted. (C) 2003 Elsevier B.V. All rights reserved.
