Silver complexes with the nido-diphosphine [7,8-(PPh2)2-7,8-C2B9H10]â have been synthesized. Reaction of [Ag(OClO3)(PR3)] with (PPh2)2C2B10H10 in refluxing ethanol affords the three-co-ordinate complexes [Ag(PPh2)2C2B9H10}(PR3)](PR3= PPh31 or PPh2Me 2), whereas treatment of [Ag(OClO3)(PPh2)2C2B10H10}] with LâL under the same conditions leads to the formation of [Ag(PPh2)2C2B9H10}(LâL)][LâL = 1,10-phenanthroline 3, bis(diphenylthiophosphoryl)methane 4 or 1,2-bis(diphenylphosphino)-1,2-dicarbadodecaborane(10)5]. The structures of complexes 1, 3 and 5 have been established by X-ray crystallography. The silver atoms show a trigonal planar (1) or tetrahedral geometry (3 and 5).
