Tetramethylammonium triphenylbis(trifluoroacetato-O)stannate crystallizes as non-interacting tetrahedral [(CH3)4N]+ cations and trans-trigonal bipyramidal [Sn(O2CCF3)2(C6H5)3]- anions. The anion is the first example of a discrete triorganostannate covalently bonded to two unidentate monocarboxylato anions.
