Abstract
The reactions of P4S3 with As4S3 and of P4Se3 with As4Se3 in the molten state yields molecules of the type P m As4−m S3 and P m As4−m Se3, respectively. A method was developed to separate the different components by the HPLC technique, and to determine their concentrations. The identification of the isomers in the HPLC pattern was achieved with the aid of the LC-MS method. In the selenium system, the distribution of the different species is statistical. In the system P4S3-As4S3, the formation of PAs3S3 with one phosphorus atom in the apical position is favoured.
