Synthesis and low-frequency vibrational spectra of some halo- and pseudohalo-diphenylantimonates(V)

subject

description

Abstract The syntheses of diphenylantimonates(V) of the type M(I) [PH 2 XbX 4 ] (M(I) = PH 4 As; X = F, Cl, Br, N 3 , NCS; X 4 = Cl 3 Br, Cl 3 N 3 ) are described. Far-Ir spectra of these compounds and of previously synthesized M(I) [Ph 2 SbCl 3 X] species (M(I) = Me 4 N; X = Cl, Br, N 3 ; M(I) = Ph 4 As; X = NCS) are reported. Raman spectra of tetrafluoro and tetrachloro salts are also given. Vibrational data are interpreted in terms of the presence of solid of trans -Ph 2 SbX 4 - species and assignments of skeletal modes are suggested.
