The preparation, spectroscopic characterisation and crystal structures of [FcP(mu- Se) Se](2), [FcP(mu-Se-2) Se](2) and [PhP(mu-Se-2) 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.
