“…These results shed light on the S-donor ability of imidazole-2-thiones. Previously, mononuclear Pd(II) complexes with imidazole-2-thiones have been reported with unsubstituted imidazole-2-thiones [26], mono-and polynuclear complexes with µ-κ 2 N,S-and S-coordinated N-substituted imidazole-2-thiones [27][28][29][30][31][32], as well as complexes with polydentate, polyfunctional ligands containing imidazole-2-thione moieties [32][33][34][35][36].…”

MoO2Cl2/MoOCl4 have been reacted with 4-phenylimidazole-2-thiol/6-mercaptopurine monohydrate/2-mercaptopyridine in acetonitrile solvent in unimolar/bimolar proportions at room temperature. The products thus obtained are: MoOCl3(C9H8N2S), [1]; Mo2O3Cl6(C9H7N2S)(CH3CN)2, [2]; Mo2O3Cl8(C9H7N2S)2(CH3CN)2, [3] and Mo2O4Cl4(C5H4NS-SN4C5), [4]. These products were studied by various techniques: infrared, proton NMR, liquid/gas chromatography-mass spectrometry, elemental analyses. Owing to the sensitivity of the products to air and moisture, the reactions and work ups were performed in vacuum line purged with oxygen by flushing dry nitrogen in it. Ions observed in mass spectrum are concurrent with the depicted formulae.

“…Absorption of terminal Mo=O group [45][46][47] (974 cm -1 ) is observed. Table 3 shows N-H stretching peak (3139 cm -1 ) in [3] of 4-phenylimidazole-2-thiol 39,[52][53][54] . No S-H stretching in the range 2551-2603 cm -1 in [3] has been observed referring that S-H group has got dissociated.…”

MoOCl4/MoO2Cl2 were reacted with 2-mercaptopyridine (IUPAC: pyridine-2-thiol)/4-phenylimidazole-2-thiol (IUPAC: 4-phenyl-1, 3-dihydroimidazole-2-thione)/6-mercaptopurine (IUPAC: 1, 7-dihydro-purine-6-thione) in acetonitrile medium using equal/twice molar concentrations at normal temperature. The reactions yielded products: MoOCl3(C5H4NS-SNH4C5).2HCl, [1]; Mo3O3Cl12(C5H4NS-SNH4C5)(CH3CN)2, [2]; Mo2OCl6(C9H7N2S)4, [3] and Mo2O2Cl8(C5H4N4S)(CH3CN), [4]. The various techniques used for characterization of compounds are: Fourier transform infrared, proton nuclear magnetic resonance, 13C nuclear magnetic resonance, liquid/gas chromatography mass spectrometry and C, H, N, S, Mo, Cl analysis. The products are prone to oxidation/hydrolysis by air/moisture, so all procedures were executed in vacuum line using dry nitrogen atmosphere. Elemental analysis and fragments recorded in mass spectrometry are in tune with the formulae proposed.
