The infrared spectrum of matrix isolated cuprous chloride

A Comparison of Structure and Stability between the Group 11 Halide Tetramers M4X4 (M = Cu, Ag, or Au; X = F, Cl, Br, or I) and the Group 11 Chloride and Bromide Phosphanes (XMPH3)4

“…Recent calculations for [CuCl] 4 support a ringlike D 4 h minimum structure instead of a heterocubane T d structure 3 , which is in agreement with the gas-phase electron diffraction experiments, with the T d structure being 26 kcal/mol higher in energy . In this study, the calculated IR spectrum is in good agreement with earlier measurements, and the gas electron diffraction also agrees with the D 4 h structure . There are a large number of experiments on group 11 halides which support oligomeric structures up to the hexamers in the gas phase.…”

Thermogravimetric analysis of InCl3 sublimation at atmospheric pressure

“…The Cu x Cu x + species are the fragments of these main three components. Similar observations were reported by Cesaro et al [38], where they used the infrared spectrometry to measure the gas-phase composition of cuprous chloride at 673 K. The primary vapor was reported to be composed of the trimer (Cu 3 Cl 3 ) and the tetramer (Cu 4 Cl 4 ).…”

Structure and stability of coinage metal fluoride and chloride clusters (MnFn and MnCln, M = Cu, Ag, or Au; n = 1–6)

“…Martin and Schaber have reported infrared absorption spectra for matrix isolated Cu n Cl n and Ag n Cl n clusters,[7] while Cesaro et al have observed frequencies of Cu 4 Cl 4 . [52] Their data are reported in Table 4 together with the present calculated values. For Cu 2 Cl 2 and Cu 3 Cl 3 the agreement between calculated and experimental values is good.…”
