The complexes of bivalent Be Mn, Fe, Co, Cu, Zn, Cd and Pb with antimony hydrogen bis(thiolactate) have been synthesised and characterised by elemental analyses magnetic measurements infrared and electronic reflectance spectral data The formation constants of the complexes formed by Be^II, Co^II, Ni^II and Zn^II ions have also been determined potentiometrically at \(30\pm\) 0.05° using Calvin-Bierrum pH-titration technique as modified by Irving and Rossotti (µ =0.01 M NaClO₄).
