The reaction of 1,5-Ph4P2N4Se2, 1, prepared by the treatment of Ph2PN2(SiMe3)3 with a mixture of SeCl4 and Se2Cl2 in acetonitrile, with 2 gives the adducts _n<η¹-N-Ph4P2N4Se2> (2, n = 1; 3, n = 2) in which the P2N4Se2 ring is shown by an X-ray structural determination of 3 to contain a transannular Se-Se interaction; the oxidative addition of 1 or 2 to Pt(C2H4)(PPh3)2 produces the corresponding η²-Se,Se' complexes.
