I. Wharf, THE ASSIGNMENT OF THE RAMAN AND FAR-INFRARED SPECTRA OF PH3SNX (X=CL,BR, I) AND PH4SN - A REAFFIRMATION, Spectrochimica acta. Part A: Molecular spectroscopy, 50(5), 1994, pp. 903-907
Complete solid state Raman (460-50 cm-1) and far-IR (460-100 cm-1) spe
ctra are reported for Ph3SnX(X = Cl, Br, I) and Ph4Sn. The assignments
reaffirm and clarify those given earlier, particularly for nu SnX and
are consistent with all Ph3SnX being monomeric. Preliminary results f
rom X-ray analysis show Ph3SnI is triclinic, space group P1BAR, with Z
= 4. The Ph3SnI molecules have almost trigonal symmetry around the ti
n while shortest intermolecular d(Sn---I) values are > 6.3 angstrom.
