The halocarbonyls BrM(CO)(5), M=Mn and Re, were reacted with the KN(SePPh2)(2) salt in equimolar amounts; the reactions were thermally carried out and resulted in the generation of the hexacoordinated isostructural complexes [M(CO)(4)Ph2P(Se)NP-(Se)Ph-2-Se,.Se'}] with a twist MSePNPSe ring conformation. Complexes' characterizations were achieved by IR, mass, NMR (H-1, C-13, (31)p, Se-77) spectroscopies, and by single-crystal X-ray diffraction. (C) 2004 Published by Elsevier B.V.
