摘      要：The title compound (Ⅰ) has been synthesized by the reaction of [RuCl2(PPh3)3], closo-[B10H10]2- and PhCH(OH)COOH in (CH3)2CHOH solution. The re-action gave two main products Ⅰ and Ⅱ. Crystals of the title compound (Ⅰ) suitable fora single crystal X-ray diffraction analysis were recrystailized from n-pentane/CH2Cl2 so-lution. Its structure was determined by X-ray crystallography analysis. The crystal of{(PPh3)2RuB10 H8 [(CH3)2CHO]2} (Ⅰ) is monoclinic, space group P21/n, Mr =860. 01, with a= 12. 927(2), b= 23. 672(6), c= 14. 090(4) A, β=93. 22(2)°, V=4305 A3, Dc= 1. 327 g/cm3, Z= 4, λ(MoKα) =0. 71073A, μ=4. 6 cm-1, F(000) =1776, R = 0. 059, Rw = 0. 075, S = 2. 62. The cluster structure is based on a closoeleven-vertex {RuB10 } polyhedron skeleton with two replacing isopropoxy and twoPPh3 groups.
