1H and 13C NMR spectroscopy of four compounds of the type [SbR3X]2O, where X = Br and R = Ph, p-tolyl and o-tolyl or X = Cl and R = Me, have been interpreted as showing that unless stringent precautions are take

Fifteen compounds of stoichiometry R3SbX2 (R = Ph or substituted aryl; X2 = Br2, I2 or IBr) were synthesized and studied by Raman spectroscopy.The crystal structure of Ph3SbI2 has been determined, which shows it to be a distorted trigonal-bipyramidal molecule.The distortion from regular trigonal-bipyramidal geometry may be explained by a pseudorotation process towards a rectangular pyramid.Moreover, there are two independent molecules within the unit cell and its distorted structure is in direct contrast to the known Ph3SbX2 (X = Cl or Br) which both adopt regular trigonal-bipyramidal geometry.The interhalogen compounds R3SbIBr also have trigonal-bipyramidal geometry.In direct contrast to the molecules Ph3El2 (E = P or As), which ionise in solution to form I, Ph3SbI2 is chemically changed in acetonitrile solution and forms the ionic I3, there being no evidence for I.The crystal structure of I3 has also been determined.
