“…The structures of its complexes with a few metal ions have also been investigated using various physical techniques (7)(8)(9). In our laboratory, we have for quite some time now been interested in the complexing properties of the HNCS group (10)(11)(12)(13).…”
The complexes of 2-mercaptobenzothiazole with Cu(II), Ni(II), Co(II), Cd(II), Zn(II), Pb(II), Tl(I), and Ag(I) have been synthesized. Their structures have been assigned on the basis of analytical, spectral (i.r. and visible), and magnetic data.

“…Mercapto-1,3-azole ligands have an important role in industry and medicine [4][5][6][7][8], and their coordination chemistry with transition metals attracted much attention [9][10][11][12][13][14][15].…”
Palladium(II) and platinum(II) complexes containing the mixed ligands tertiary diphosphines Ph 2 P(CH 2 ) n PPh 2 , (n = 1-4) and benz-1,3-imidazoline-2-thione, benz-1,3-oxazoline-2-thione or benz-1,3-thiazoline-2-thione have been prepared and characterized by elemental analysis, magnetic susceptibility, molar conductance and i.r. spectral data. 31 P-{ 1 H}-n.m.r. data have been applied to characterize the produced linkage isomers.
“…Further, the compound is used as a precipitant for gravimetrie analysis of many metals [2]; it has found applications in the vulcanization of rubber [3] and as a corrosion inhibitor [4]. Several metal complexes of merBtz have been reported in the literature [5]. These complexes could form mixed ligand complexes with nitrogen-containing ligands [6].…”
The reactions of bis(2-mercaptobenzothiazolato)nickel(II) with some azoles and morpholine afforded the corresponding mixed ligand complexes. The studied azoles were 2-aminothiazole, benzothiazole, benzoxazole, 2-methylbenzoxazole and 2-mercapto-benzoxazole. The formation of new compounds was confirmed from the spectral data. The thermal decompositions of the compounds together with some related compounds reported in the literature, for comparison, were studied. The activation energies and other kinetic parameters were calculated from the Coats-Redfern and Horowitz-Metzger equations.2-Mercaptobenzothiazole(merBTz) exhibits biological activity in the sense that it can cause inhibition of tumour tissue [1]. Metal chelation is most probably involved in this effect. Further, the compound is used as a precipitant for gravimetrie analysis of many metals [2]; it has found applications in the vulcanization of rubber [3] and as a corrosion inhibitor [4]. Several metal complexes of merBtz have been reported in the literature [5]. These complexes could form mixed ligand complexes with nitrogen-containing ligands [6].Due to the above-mentioned particular importance of merBtz and because oxazole and thiazole derivatives are being used as analytical reagents in both industry and medicine [7,8], we embarked on a study of the interaction of Ni(merBtz)2 with a number of azoles and morpholine (morph).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
