Three nido 11-vertex platinaundecaborane clusters: [(PPh3)2PtB10H11-9-O-i-Pr] (1), [(PPh3)2PtB10H10-8,10-(O-i-Pr)2] (2) and [(PPh3)2PtB10H11-8-O-i-Pr] (3) were obtained from the reaction of [PtCl2(PPh3)2] with (Et4N)2B10H10 in i-PrOH under reflux conditions. They all have a nido 11-vertex PtB10 polyhedral skeleton, in which Pt atom lies on the open PtB4 face. Each Pt atom was connected with four B atoms and two P atoms of PPh3 ligand. Two novel B10H102- deboronated nido 11-vertex diplatinaundecaboranes: [(PPh3)2(μ-PPh2)Pt2B9H6-3,9,11-(O-i-Pr)3] (4) and [(PPh3)2(μ-PPh2)Pt2B9H6-3,9-(O-i-Pr)2-11-Cl] (5) were obtained when the same reaction was carried out under solvothermal conditions. Cluster compounds 4 and 5 have a nido 11-vertex Pt2B9 polyhedral skeleton, in which two Pt atoms stay at neighbouring positions of the open Pt2B3 face and bridged by a PPh2 ligand. Each Pt atom was connected with three B atoms and a P atom of PPh3 ligand. They were characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction.

Key words: nido configuration, platinaborane, cluster, solvothermal synthesis, crystal structure
