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{single bond}H), ν(C{double bond, long}O), ν(C{single bond}N) and ν(C{double bond, long}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.
