Reactivity of [MO]3+ (MÂ =Â Tc, Re) core towards 2-mercapto-1,3-azole ligands. Formation of a new organometallic complex of Re(IV) and X-ray crystal structures

Reactions of [MOCl4]− anion (M = Re, Tc) with imidazole-2-thiol ligands H2Ln give bi- and tetra-substituted complexes [MOCl2(H2L)2 (H2O)]+ and [MO(H2L)4]3+. An organometallic species is formed from reaction of [ReOCl3(PPh3)2] and benzoxazole-2-thiol ligand HL5 by a desulfurization process.
