Abstract

The gas-phase structure of chloromethylphosphine, CClH2PH2, has been determined by electron diffraction employing constraints derived from ab initio computations at the CISD (fc) 6− 31+ G∗∗ level. At 293K, the compound exists in two conformations, anti and gauche (phosphorus lone pair relative to the C Cl bond); the mole fraction of the gauche conformer is 0.22 (5). Important experimental structural parameters (rg/pm,∠ α/deg) for the anti and ...
