Abstract
A dry benzene solution of the Schiff base N-(2-hydroxymethylphenyl)-3′-carboxy-2′-hydroxybenzylideneimine upon reacting with mercaptoacetic acid undergoes cyclization and forms N-(2-hydroxymethylphenyl)-C-(3′-carboxy-2′- droxyphenyl) thiazolidin-4-one, LH3 (I). A MeOH solution of I reacts with Co(II), Ni(II), Cd(II), Zr(OH)2(IV), and UO2(VI) ions and forms the monomeric coordination compounds, [M(LH)(MeOH)3] [where M = Co(II), Ni(II)], [M′(LH)(MeOH)] [here M′ = Cd(II), UO2(VI)] and [Zr(OH)2(LH)(MeOH)]. The coordination compounds have been characterized on the bases of elemental analyses, molar conductance, molecular weight, spectral (IR, NMR, and reflectance) studies, and magnetic susceptibility measurements. I behaves as a dibasic tridentate OOS donor ligand in these compounds. The compounds are nonelectrolytes (AM = 3.8-8.9 mho cm2 mol−1) in DMF.
