Abstract
The synthesis and characterization of three of the six possible linkage isomers of SnPh(2)(B5H8)(2) is reported, reaction between K[B5H8] and SnCl(2)Ph(2), in 2:1 molar ratio, affording either mu,mu'-SnPh(2)(B5H8)(2), 1, mu,2'-SnPh(2)(B5H8)(2), 2, or mu, 1'-SnPh(2)(B5H8)(2), 3, depending on the choice of solvent and conditions; the crystal structures of 2 and 3 are reported and 3 is also prepared in the reaction between K[B5H8] and 1-SnClPh(2)B(5)H(8).

Abstract
Six new oxalato chlorodiorganostannic derivatives and adduct have been synthesized, their infrared and Mossbauer studies carried out Polymeric structures have been suggested, the oxalate behaving as a monochelating or a bichelating donor R2NH2+ cations, when involved, lead to supramolecular structures.
