The tetrasubstituted polyanions of platinum, palladium, and gold [M(SnB11H11)(4)](x-) (x = 6, M = Pd, Pt; x = 5, M = Au) have been prepared and characterized by single-crystal X-ray diffraction, elemental analysis, IR, Raman, B-11, and Sn-119 heteronuclear NMR spectroscopy. In the case of the platinum derivative [Bu3MeN](6)[Pt(SnB11H11)(4)] (2) Sn-119 Mossbauer spectroscopy has been carried out. The isolated salts are stable towards moisture and air and the complexes 2 and 3 were treated with 1,3-bis(diphenylphosphino)propane (dppp) to give the respective substitution products [Bu3MeN](2)[(dppp)M(SnB11H11)(2)] (M = Pd, Pt).
