The tin nucleophile [SnB11H11]2– reacts with the gold cluster [Au9(PPh3)8][NO3]3 under formation of the tin–gold complex [Au8(PPh3)7(SnB11H11)] (1). In reaction with four equivalents of the heteroborate a mixed valence tetrahedral gold cluster [Au4(PPh3)4(SnB11H11)2]2– with two edge bridging tin ligands was isolated. The reaction products were characterized by elemental analysis, NMR spectroscopy and single crystal X-ray crystallography.
