- Display Note: Abstract: The geometries and vibrational frequencies of the adducts ClCO2, ClCOS and ClCS2 were derived at the Hartree-Fock (HF) 3-21G (∗) level. The Ca, structure of ClCO2 corresponds to one C-O bond and one C=O bond. Similarly, Ca, ClCS2 has one C-S and one C=S bond, and ClCOS has one C-S and one C-O bond. Single-point spin-projected fourth-order Møller-Plesset (MP4) 3-21G (∗) calculations at these geometries were used in bond-separation reactions to derive ΔHo0 for adduct formation, which is calculated to be about 39 kJ mol−1 exothermic for ClCOS and ClCS2, but about 39 kJ mol−1 endothermic for ClCO2. The C2v structures for ClCO2 and ClCS2 were also characterized. The geometry of ClCS2 has not been determined experimentally; comparison with an available measured entropy for ClCS2 suggests that the C2v structure is the one formed by addition of Cl to CS2, although the energy relative to the Ca form is not reliably calculated because of instability in the HF wavefunction.
