Physico-Chemical Studies on the Coordination Compounds of Thiazolidin-4-One

A dry benzene solution of the Schiff base, N-(2-hydroxyphenyl)-3 � -carboxy-2 � -hydroxybenzylideneimine upon reacting with mercaptoacetic acid undergoes cyclization and forms . e coordination compounds have been characterized on the basis of elemental analyses, molar conductance, molecular weight, spectral (IR, re�ectance, ESR) studies, and magnetic susceptibility measurements. I behaves as a dibasic tridentate OOS donor ligand in these compounds. e compounds are nonelectrolytes (Λ M = 6.2-13.8 mho cm 2 mol −1 ) in DMF. A square-planar structure for III; a tetrahedral structure for IV and an octahedral structure for II, V, and VI are suggested
