Abstract

The preparation, spectroscopic characterisation and crystal structures of [FcP(µ-Se)Se]2, [FcP(µ-Se2)Se]2 and [PhP(µ-Se2)Se]2 are reported. Crystallographic data reveal planar four-membered PSePSe and skewed six-membered P2Se4 rings, 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.
