Two dibenzyltin compounds,{[C_6H_5O(O)C=N-N=C(Ph)COO] (m-Cl-C_6H_4CH_2)_2-Sn(CH_3OH)}_2(1) and {[p-Me-C_6H_4O(O)C=N-N=C(Ph)COO] (m-Cl-C_6H_4CH_2)_2Sn(CH_3OH)}_2 (2),have been synthesized by microwave "one pot" reaction with benzoylhydrazine (or p-methyl benzhydrazine),phenylglyoxylic acid and di-m-chlorobenzyltin dichloride.Compound 2 contains two crystals 2a and 2b.The compounds have been characterized with IR,elemental analysis,~1H,~(13)C and ~(119)Sn NMR spectra,H RMS.Three crystals are all binuclear molecules with a Sn_2O_2 four-membered ring plane,and each Sn atom center is seven-coordina...
