A flow injection analysis (FIA) incorporating a thiosemicarbazone-based coated wire electrode (CWE) was developed method for the determination of mercury(II). A 0.1 M KNO(3) carrier stream with pH between 1 and 5 and flow rate of 1 mL·min(-1) were used

Cyclometallated palladium(ii) and platinum(ii) pyrenyl-derived thiosemicarbazone (H2PrR) complexes of the type [M4(μ-S-PrR-κ3-C,N,S)4] (M = PdII, PtII; R = ethyl, cyclohexyl) have been synthesised in good yields and fully characterised. X-ray crystallography showed that the tetranuclear complex [Pt4(μ-S-PrCh-κ3-C,N,S)4](CH3)2COCHCl3 contains an eight-membered
