Simple mechanochemical preparation of dichloromonothiosemicarbazidezinc(ii)†

Dichloromonothiosemicarbazidezinc(II), with the molecular formula ZnCl₂[CH₅N₃S], has been prepared via a fast, easy, and reproducible mechanochemical method. Coordination compounds using first-row transition metals with ligands of thiosemicarbazide, thiosemicarbazone, or their derivatives have been of recent interest for their antibacterial and antifungal properties. Thus, bringing greener synthesis methods to the table for production of such useful compounds is desirable. The pure product, ZnCl₂[CH₅N₃S], was characterized using X-ray powder diffraction, proton nuclear magnetic spectroscopy, infra-red spectroscopy, melting point, and magnetic susceptibility measurements.
