Abstract

The crystal structure of tetrakis(triphenylphosphine)silver(I)bis(trifluoroacetato) triphenylstannate(IV), [(C₆H₅)₃P]₄Ag (C₆H₅)₃Sn(O₂ CCF₃)₂ [R3: a = 16.238(1), c = 52.354(3) Å], consists of discrete four-coordinate tetrahedral 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 R_F = 0.053.
