Abstract

The preparation, spectroscopic characterisation and crystal structures of [FcP(µ-Se)Se]₂, [FcP(µ-Se₂)Se]₂and [PhP(µ-Se₂)Se]₂are reported. Crystallographic data reveal planar four-membered PSePSe and skewed six-membered P₂Se₄rings, respectively, in all cases with trans arrangement of organic substituents and exo selenium atoms. Whilst stable at room temperature in solid state, NMR data suggest the six-membered rings of both the ferrocenyl and phenyl compounds decompose in the solution with loss of red selenium, forming PSe₂PSe five-membered rings.
