Abstract

Abstract The infrared spectra (380-40 cm −1) of the triphenylphosphine (L) complexes L 2MX 2 and (LHgX 2) 2, M = Zn, Cd, or Hg; X = Cl, Br, or I, have been recorded. Assignments are proposed for the M—X stretching, XMX bending, and M—P stretching frequencies of the L 2MX 2 complexes, and the terminal Hg—X stretching frequencies of the (LHgX 2) 2 complexes. The M—P stretching frequencies are at ∼160 cm −1 (M = Zn); ∼135 cm −1 (M = Cd); and ∼130 and 105 cm −1 (M = Hg), but they could not be identified for the (LHgX 2) 2 complexes.
