Seven compounds containing tin-copper bonds, namely [Ph2P(CH2)(n)PPh2](CuSnPh3)(2) (n=1-4) and (Ph2PR)CuSnPh3 (R=Ph, Bu, Am), have been synthesized.

Tin-119 Moessbauer spectra for these compounds were determined. The results have shown that the QS values for these compounds are all zero, the IS values are between 1.32 and 1.38 mm/s, and the oxidation state of tin is +4.展开更多
