The rhenacarborane salt Cs[Re(CO)3(eta5-7,8-C2B9H 11)] (1) has been synthesized in excellent yield using a new procedure. Treatment of CH2Cl2 solutions of 1 with [RuCl2(PPh3)3] yields the exo-closo complex [Re(CO)3(eta52,3,10-(mu-H) 3-exo-{RuCl(PPh3)2}-7,8-C2B 9H8)] (2a). In this molecule a [RuCl(PPh3)12]+ moiety is exopolyhedrally bound via three B – H – Ru bonds to a closo-3,1,2-ReC2B9 system. An X-ray diffraction study revealed that one of these agostic interactions utilizes a beta-B-H bond in the coordinating CCBBB face of the cage, while the source of the remaining two B – H – Ru bonds is in the 65 belt. The anion of salt 1 also binds exopolyhedral [Rh(PPh3)2]+ and [Rh{Fe(eta-C5H4PPh2)2}] + fragments in the complexes [Re-(CO)3(eta5-5,10-(mu-H)2-exo-(RhL 2)-7,8-C2B9H9)] (L2 = (PPh3)2 (3a), {Fe(eta-C5H4PPh2)2} (3b)). Reaction of 1 with the salts [M(CO)2(THF)(eta-C5H5)] [BF4] (M = Fe, Ru) and [Fe(CO)2(THF)-(eta-C5Me5)][BF4] gives the complexes [Re(CO)3(eta5-n-(muH)-exo-{M(CO) 2(eta-C5R5)}-7,8-C2B 9H10)] (M = Fe, R = H, n = 10 (4a); M = Ru, R = H, n = 10 (4b); M = Fe, R = Me, n = 10 (4c), 9 (4d)) with isomers 4c and 4d formed as an inseparable mixture. An X-ray structural study on 4b revealed that there was no Re-Ru bond and that an exro-[Ru(CO)2(eta-C5H5)]+ fragment is bound to the rhenacarboranyl anion by a single unsupported B – H – Ru interaction with an unusually long B – Ru distance (2.695(13) A). The compounds [ReM(mu-10-H-eta5-7,8-C2B9H 10)-(CO)3(PPh3)] (M = Cu (5a), Ag (5b)) were isolated from the reaction of 1 with sources of the fragments [M(PPh3)]+ (M = Cu, Ag). X-ray structure determinations of both species 5 revealed the presence of direct Re – M (M = Cu, Ag) connectivities bridged by carborane beta-B – H – M interactions. In solution the complexes 5 are highly dynamic on the NMR time scale, even at low ( – 90C) temoeratures.
