Synthesis and spectroscopic studies of mixed catechol-salicylaldiminate derivatives of antimony (III)‎ and tin (TV)‎

الملخص EN

Mixed catechol- salicyladiminenate derivatives of antimony (III) and tin (IV) of the general formula M(cate)Ln]X, [where : M = Sb, x = 0 ; M = Sn, x = €؛١ cate = catcehol; n = l, L = aniline, 11 = 2, L = m-bromo-aniline, n = 3, L=p-bromoaniline] were prepared by the reaction of equimolar amount of [(cate)MCln], [where n=l or 2J with N-arylsalicylaldimines HOCf, H4Ctl = NC(M ; (HL1), HOC6H4CH= NC6H4 (HL1) and p-IIOCcH+CH = NCfi^Br (HL ) methanol as a solvent.

These new derivatives were eharactcriscd by elemental analysis and spectroscopic methods [(I.R), (L'.V-Vis) and (1H, لا€ NMR for ا IL2)] along with conductivity and melting point measurements.

These studies revealed that the geometry' about Sb (III) and Sn (IV) is tetrahedral-
