CS2 elimination and C–S bond cleavage in [Zn(dmpzdtc)2] – Leading to formation of a cyclic octanuclear complex [Zn4(μ-dmpz)5(μ-OH)(μ3-S)(py)]2 · py(dmpzdtc = 3,5-dimethylpyrazole-1-dithiocarboxylate, dmpz = 3,5-dimethylpyrazolate)

Complex [Zn(dmpzdtc)2] (1) (dmpzdtc = 3,5-dimethylpyrazole-1-dithiocarboxylate) in MeCN and pyridine underwent unique CS2 elimination and C–S bond cleavage reactions to afford a novel cyclic octanuclear zinc sulfide complex [Zn4(μ-dmpz)5(μ-OH) (μ3-S)(py)]2 · py (2 · py) dmpz = 3,5-dimethylpyrazolate). Single-crystal X-ray diffraction revealed that 2 consists of two [Zn4(μ-dmpz)3(μ-OH)(μ3-S)(py)] fragments linked by two pairs of μ-dmpz ligands, forming an unique metallocyclic structure. The luminescent property of this complex in solid state was also investigated.
