✦ Synopsis
chlorine split-off is manifested by contraction of the OPCl angle from 115 to 109" and by that of the SPCI angle from 116 to 110°C. According to the calculations, the P=O and P=S bond lengths are 1-2pm shorter and the PCI distances 6 pm longer than in the corresponding trichlorides.
The dehalogenation of the oxide chlorides is due to the thermal instability of Ag,O above 570 K; by this route, numerous other molecules containing central atoms with low coordination number can be prepared, e.g. OPF[lal, OPBr""], SPF""], OAsCI[Iq, OSbCPq, and 02PCl['g1.
