The reaction of PtCl2(PPh3)2 with closo-[B10H10]2- in t-BuOH under reflux (70 h) unexpectedly afforded the nido 11-vertex platinaborane [(PPh3)2PtB10H10-9,10-(H0.7Cl0.3)2] 1, which was characterized by single-crystal X-ray diffraction study. Crystallographic data for 1: C36H41.40B10Cl0.60P2Pt, Mr = 860.49, triclinic system, space group P1, a = 11.255(2), b = 11.623(2), c = 17.148(3) , α = 81.012(2), β = 88.115(3), γ = 64.322(2)°, V = 1995.4(7) 3, Z = 2, Dc = 1.432 g/cm3, μ(MoKα) = 3.662 mm-1,F(000) = 851, R = 0.0358 and wR = 0.0951. Compound 1 has a nido 11-vertex {PtB10} polyhedral skeleton with the Pt atom lying in the open PtB4 face and further ligating to two PPh3 ligands. 1 is partially chlorinated at positions B(9) and B(10), and for each chlorine atom an occupancy factor of 0.3 is given by crystallography.
