Zusammenfassung: 
Two isomers of each of alpha-P4S2SeI2 and alpha-P4SSe2I2 have been identified by P-31 and Se-77 NMR spectroscopy in mixtures made by direct combination of the elements. The same compounds were formed as a result of a photochemical redistribution reaction between alpha-P4S3I2 and alpha-P4Se3I2 in solution in CS2. Systematic changes in chemical shifts and in coupling constants with alterations in molecular geometry, as sulfur was replaced by selenium in the series alpha-P4S3I2 1 - alpha-P4S2SeI2 2,3 - alpha-P4SSe2I2 4,5 - alpha-P4Se3I2 6, are reported.
