GOLD(I) COMPLEXES WITH THE LIGAND 1-THIOLATE-1,2-DICARBA-CLOSO-DODECABORATE - CRYSTAL-STRUCTURE OF [AU-2(1-S-1,2-C2B10H11)(2)(MU-DPPE)]

Neutral and anionic gold(I) mononuclear derivatives with the 1-thiolat e-1,2-dicarba-closo-dodecaborat ligand of stoichiometries [Au(1-S-1,2- C2B10H11)L] and [Au(1-S-1,2-C2B10H11)(2)](-) have been synthesised. Th e complex [Au(1-S-1,2-C2B10H11)(AsPh3)] is a good starting material fo r the synthesis of the dinuclear gold(I) derivative [Au-2(1-S-1,2-C2B1 0H11)(2)(mu-PP)], where PP is a diphosphine. The compound [Au-2(1-S-1, 2-C2B10H11)(PPh3)(2)]BF4 has also been prepared. The structure of the neutral complex [Au-2(1-S-1,2-C2B10H11)(2)(mu-dppe)] is confirmed by s ingle-crystal X-ray diffraction. There are no short gold-gold interact ions. (C) 1998 Elsevier Science S.A. All rights reserved.
