## Abstract Two organotin (IV) derivatives, [Bu~2~β Sn(HO~3~POβ__i__βPr)~2~]~2~ (1) and [Bu~2~Sn(HO~3~POPh)~2~]~2~ (2), have been prepared by reactions of diβ__n__βbutyltin oxide with the phenylphosphoric acid and isopropylphosphoric acid, respectively. Characterization of the complexes 1 and 2 was
Values of coupling constants )2J("9Sn, 'H)), determined from 'H NMR spectra, gave estimates of C-Sn-C angles in Me,SnL in the range 128-136 O in methanol and aqueous solutions, which correspond to values from Il9Sn Mossbauer AE parameters (129.6-133.8 "). The structural relationship of R2SnL molecul
