  Treatment of Cs[3,3,3-(CO)3-closo-3,1,2-ReC2B9H11] 1 with [Pt(NCMe)2Ph2P(CH2)2PPh2}][BF4]2 yielded [3,3,3-(CO)3-3,8-(PtPh2P(CH2)2PPh2})-8-(μ-H)-closo-3,1,2-ReC2B9H10][BF4] 2b as the sole product. The cation of salt 2b is a bimetallic species with a Re–Pt bond bridged by a nido-7,8-C2B9H11 ligand pentahapto coordinated to the rhenium and with the β-B–H bond in the ligating CCBBB ring of the carbaborane cage forming a 3-centre 2-electron B–H⇀Pt bond. Deprotonation of 2b with strong bases gives an isomeric mixture of the complexes [3,3,3-(CO)3-3,n-(PtPh2P(CH2)2PPh2})-closo-3,1,2-ReC2B9H10] 3a (n = 4), 3b (n = 8). The isomers are readily separated and the proportion of 3a to 3b formed is solvent- as well as base-dependent. In THF solutions of 2b afford a 1∶3∶1 equilibrium mixture of 2b, 3a, and 3b. Refluxing THF solutions of 1 with [Pt(H)(THF)(PEt3)2][BF4] for several days yields a separable mixture of the isomers [3,3,3-(CO)3-3,n-Pt(PEt3)2}-closo-3,1,2-ReC2B9H10] 4a (n = 4), 4b (n = 8). The same reactants, when stirred together in CH2Cl2 at ambient temperatures, give 4a and [3,3,3-(CO)3-3,8-Pt(H)(PEt3)}-8-(μ-H)-closo-3,1,2-ReC2B9H10] 5. Complex 4a, not 5, is the precursor to 4b, the interconversion occurring at elevated temperatures in solution by an intramolecular exchange of B–Pt σ bonds between α-B and β-B vertices in the coordinating CCBBB face of the cage. Treatment of 1 with [Pt(Me)(THF)(PMe2Ph)2][BF4] at room temperature initially gives [3,3,3-(CO)3-3,4-Pt(PMe2Ph)2}-closo-3,1,2-ReC2B9H10] 6a. However, 6a isomerizes in CH2Cl2 solutions at ambient temperatures to give a 1∶1 mixture of 6a and [3,3,3-(CO)3-3,8-Pt(PMe2Ph)2}-closo-3,1,2-ReC2B9H10] 6b. The NMR data (1H, 13C, 11B and 31P) for the new complexes are discussed.

  Treatment of the long-known compound Cs[3,3,3-(CO)(3)-eloso-3,1,2-ReC2B9H11] with [N(C6H4Br-4)(3)][SbCl6] in the presence of Me3NO in THE (tetrahydrofuran) has led to the formation of [HNMe3][3,3-(CO)(2)-3,3-Cl-2-closo-3,1,2-ReC(2)BgH(11)] in good yield. Structural characterization of this compound has identified it as a four-legged piano stool half-sandwich complex anion resulting from oxidation of rhenium by both the aminium and hexachloroantimonate ions and CO displacement promoted by Me3NO in the presence of by-product chloride ions. Direct iodination of Cs[3,3,3-(CO)(3)-closo-3,1,2-ReC2B9H11] has yielded [3,3,3-(CO)(3)-3-I-closo-3,1,2-ReC2B9H11 1], which undergoes iodide migration in donor solvents from the metal to the beta-B vertex in the coordinating CCBBB face of the cage. The resulting complex anion, [3,3,3-(CO)(3)-8-I-closo-3,1,2-ReC2B9H10](-), whose structure has been confirmed by X-ray diffraction, has been shown to be luminescent in MeTHF at 77 K(lambda(em) = 455 nm) and electroactive in solution at ambient temperatures, undergoing a quasi-reversible two-electron oxidation to a proposed Re-III cationic rhenacarborane species in MeCN solutions. By contrast, two fully reversible sequential one-electron oxidations have been observed in CH2Cl2 solutions. (c) 2004 Elsevier B.V. All rights reserved.
