The presence of two different chromophores in benzothiazole molecule namely benzothiazole and aromatic rings lead to interesting chemical and biological properties that attract more researches on the compounds. Three new benzothiazolylbenzoythiourea compounds namely 1- (1,3-benzothiazol-2-yl)-3-(benzoylthiourea) (BBT),

Aroylthiourea ligands, 1-aroyl-3-cyclohexyl-3-methylthiourea (HL 1), 1-(2-chloroaroyl)-3-cyclohexyl-3-methylthiourea (HL 2), 1-(3-chloroaroyl)-3-cyclohexyl-3-methylthiourea (HL 3) and 1-(4-chloroaroyl)-3-cyclohexyl-3-methylthiourea (HL 4) were synthesized through a condensation reaction of methylcyclohexylamine and aroylisothiocyanate with a general formula (X-Ph)(CO)NH(CS)N(C 6 H 5)(CH 3) where X = H, o-Cl, m-Cl and p-Cl, fully characterized by CHNS micro elemental analysis, infrared spectroscopy, UV-visible, nuclear magnetic resonance (1 H, 13 C) and X-ray crystallography. 1-(3-chloroaroyl)-3-cyclohexyl-3-methylthiourea (HL 3) crystallized in the monoclinic system, a=14.504(3), b=4.9599(11), c=22.325(5) Å, β=98.461(7)°, Z= 4 and V=1588.5(6) Å with space group P2 1 /c. The IR spectra of the ligands exhibits the characteristic v(CO) and v(N-H) at range 1701-1640 cm-1 and 3317-3144 cm-1 , respectively. Whereas the 1 H and 13 C NMR spectra shows the resonances for N-H and-CO groups at range 8.3-8.5 and 160-163 ppm, respectively. A onepot reaction involving the aroylthiourea ligand, oxovanadium(IV) ion and potassium hydrotris(3,5-dimethylpyrazolyl) borate (KTp*) complex gave the desired [oxovanadium(IV)(tris(pyrazolyl)borate)(aroylthiourea)] complexes namely
