Abstract
Abstract Three new compounds, N-(3,4-dichlorophenyl)-N′-(2-methylbenzoyl)thiourea (2a), N-(3,4-dichlorophenyl)-N′-(3-methylbenzoyl)thiourea (2b) and N-(3,4-dichlorophenyl)-N′-(4-methylbenzoyl)thiourea (2c) are isomers which have been successfully synthesised and characterised by typical spectroscopic techniques, namely IR and 1H and 13C multi-nuclear magnetic resonance (NMR). The structure of 2a was determined by single crystal X-ray diffraction method and crystallised in the monoclinic system with space group C2/c, adopting configuration of the molecule is trans–cis. The infrared spectra of these compounds showed four significant stretching vibrations of ν(N H), ν(C O), ν(C N) and ν(C S) at 3261–3279 cm−1, 1662–1680 cm−1, 1345–1379 cm−1 and 688–738 cm−1, respectively. The 13C NMR chemical shift for the thiourea moiety appeared at ca. δC 180 ppm.
