1,2-Carbastanna-closo-dodecaborate, a New Tin Ligand in Coordination Chemistry: Synthesis, Structure, and Reactivity

The synthesis of [MePPh3][SnCB10H11] is presented together with its structural, NMR, and 119Sn Mössbauer spectroscopical characterization. Two transition metal complexes, [Au4(PPh3)4(SnCB10H11)2] and [Bu4N]2[Rh(PPh3)2(SnCB10H11)3], with the carbastannaborate coordinated at rhodium or gold via the tin atom are presented, and the structural and NMR spectroscopical data are discussed.
