The crystal structure of tetrakis[m-(trifluoromethyl)phenyl]tin(IV), [
Sn(C6H4CF3)4], has been determined. The Mossbauer spectrum of the comp
ound shows a single peak with an isomer shift of 1.20 mm s-1. The mole
cule is tetrahedral with no short intermolecular contacts. The Sn atom
is located at a special position and the four Sn-C bond lengths [2.14
3 (5) angstrom] are equal by symmetry.
