“…Structural features of organotin chelates and molecular adducts with Schiff bases are markedly influenced [3][4][5][6][7][8][9][10] by the number and nature of alkyl/aryl groups attached to tin as well as to azomethine nitrogen atom. In order to investigate the role of steric demand of the group attached to the donor nitrogen atom in influencing the stereochemical aspects of organotin(IV) complexes, we have carried out reactions of dimethyltin diisopropoxide/dimethyltin dichloride and butyltin triisopropoxide with a number of sterically hindered N-arylsalicylaldimines such as HOC 6 H 4 CH=NC6H 3 Me2-Anirudh Singh et cd.…”

Biologically potent tetraazamacrocyclic heterobimetallic complexes of silicon, tin, titanium, zirconium and platinum have been synthesized by the reactions of monometallic [Pt(C 4 H i3N 3 ) 2 ]Cl 2 with organometallic compounds of silicon, tin, titanium and zirconium in 1:2 molar ratios in methanol. The complexes were characterized by physicochemical and spectroscopic methods and a square planar geometry has been suggested for the resulting macrocyclic complexes. These have been screened for their antimicrobial activity against several microbes and the results are compared with the starting materials. INTRODUCTIONTransition metal complexes of binucleating ligands 1 are of interest because they provide the opportunity to study the intramolecular binding and possible activation of small substrate molecules between the metal centres, along with magnetic exchange infractions and multielectron redox reactions. They may also serve as models for certain metal loproteins'. Heterobimetallic transition metal complexes have received much attention in recent years 3 . Many types of binuclear complexes with bridging ligands have been synthesized and used in studies of electron-transfer processes and metal-metal infractions 4 . Bridging ligands can change the nature of metal-metal interactions. For example, studies on binuclear complexes with bridging imidazolate ligands suggest that imidazolate is particularly efficient in promoting electron transfer 5 .The chemistry of multimetallic systems is an emerging area of material science as documented by the increase in the number of publications . Various metals have been incorporated in all of the topologically different parts of dendritic structures providing new materials which, in some cases have been shown to possess interesting properties in catalysis 7 ' 8 , electrochemistry, photophysics 9 and as molecular sensor for gas. Electron transfer processes in binuclear ruthenium complexes have been the subject of interest due to the fact that these play vital roles in industrial endeavors as well as in biological organisms 10 . In addition, these complexes have been used as homogenous catalysts for the hydrogenation of unsaturated substrates". Platinum metal have attracted considerable interest owing to their anticancer activity and biological activity 12 . In the present paper, we have made an attempt for the synthesis and characterization of new heterobimetallic complexes of platinum and group fourteen elements.
