Reaction of (Ph2PCl)> with (Me3Si)2Se. The Crystal Structures of 2Se>, (Ph2P)2Se> and (Ph2P)2Se>

Phosphorus, Selenium, Chromium Complexes, Crystal Structure The reaction of (Ph2PCl)> with (Me3Si)2Se in toluene at 298 K leads to the compounds 2Se> (1) and (Ph2P)2Se> (2).If the reaction is carried out in ether as solvent at 308 K, (Ph2P)2Se> (3) is obtained.The structures of 1, 2 and 3 were determined by single crystal X-ray analysis. 1, 2 and 3 contain the Ph2PSePPh2 ligand, which is coordinated to chromium carbonyl fragments in three different ways. 1 consists of a dinuclear complex in which two fragments are linked by a Ph2PSePPh2 group.In 2, only one phosphorus atom of the Ph2PSePPh2 ligand is bound to a unit.In 3, the Ph2PSePPh2 group is coordinated as a chelate ligand to a fragment.
