Abstract
The crystal structure of tetrakis(triphenyl-phosphine)silver(I)bis(trifluoroacetato)triphenylstannate(IV), [(C6H5)3P]4Ag (C6H5)3Sn(O2CCF3)2 [R3: a = 16.238(1), c = 52.354(3) Å], consists of discrete four-coordinate te trahedral cations and five-coordinate trans-C3SnO2 trigonal bipramidal anions. The asymmetric unit consists of a third of each of two cations and two anions. The structure is a 0.675(3): 0.325 twin of a 0.783(1): 0.217 disorder of an R3 structure that uses a 2-fold rotation operation of R32 for the twinning and the disorder. The structure is refined on 234 variables and 6276 reflections with I > 3σ(I) to RF = 0.053.
