title: Novel carbon-centred reactivity of [(H)C(PPh2Se)2]- in the formation of structurally diverse Sn(IV), Te(IV) and Hg(II) complexes of the triseleno ligand [(Se)C(PPh2Se)2]2-.
abstract: Metathetical reactions between TMEDA.Li[(H)C(PPh(2)Se)(2)] and MCl(2) (M = Hg, Sn, Te) in a 2 : 1 molar ratio afforded the homoleptic complexes, {M[(H)C(PPh(2)Se)(2)](2)}, as intermediates which undergo a surprising selenium/hydrogen exchange at the carbon centre to yield the dianionic triseleno ligand in {M(n)[(Se)C(PPh(2)Se)(2)](2)} (n = 1, M = Sn, Te; n = 2, M = Hg).
