Reaction of 1,3-{(Ph2P)(2)N}(2)C6H4 or 2,6-{(Ph2P)(2)N}(2)C5H3N with elemental sulfur or selenium in CH2Cl2 affords the corresponding tetrasulfide or tetraselenide, respectively, in good yield. The complexes [1,3-{Mo(CO)(4)(Ph2P)(2)N}(2)(C6H4)] and [2,6-{Mo(CO)(4)(Ph2P)(2)N}(2)(C5H3N)] were prepared from the reaction reaction of these phosphinoamines with [Mo(CO)(4)(nbd)] (nbd = norbornadiene) in toluene, and the structure of the latter complex has been determined by single-crystal X-ray diffraction analysis.phosphorus-nitrogen chemistrymetal-carbonyl-complexes(ph2p)(2)nhdppaclusterstext::journal::journal article::research article
