Abstract

Reaction of Pt(PPh3)3 with Se4N4 in CH2Cl2 leads to a mixture of Pt(Se2N2)(PPh3)2 (1) and an intermediate species, which decomposes via loss of PPh3 to give [Pt(Se2N2)(PPh3)]2·CH2Cl2 (2). X-ray crystallography reveals 2 to be dimeric, with [Pt(Se2N2)(PPh3)] units bridged by PtN bonds in a Pt2N2 ring. The central [PtSe2N2]2 core is planar and the geometry of the individual PtSe2N2 rings is comparable to that in the only other example reported, [Pt(Se2N2H)(PMe2Ph)2]Cl.
