Sw. Ng et Vgk. Das, THE FIRST EXAMPLE OF A DISCRETE DI(CARBOXYLATO)TRIORGANOSTANNATE - TETRAMETHYLAMMONIUM TRIPHENYLBIS(TRIFLUOROACETATO)STANNATE, Acta crystallographica. Section C, Crystal structure communications, 53, 1997, pp. 212-213
Tetramethylammonium triphenylbis(trifluoroacetato-O)-stannate crystall
izes as non-interacting tetrahedral [(CH3)(4)N](+) cations and trans-t
rigonal bipyramidal [Sn(C2F3O2)(2)(C6H5)(3)](-) anions. The anion is t
he first example of a discrete triorganostannate covalently bonded to
two unidentate monocarboxylato anions.
