5-trans-(Et3P)2Pt(H)}-(µ3,4-H)(µ5,6-H)-2-CB5H6]. The molecular structure of [nido-µ4,5-trans-(Et3P)2Pt(H)}-µ5,6-H-2,3-C2B4H6] has been established by a single-crystal X-ray diffraction study. Four molecules crystallise in the monoclinic space group P21/m with cell dimensions a= 10.970(4), b= 11.587(3), c= 9.459(3)Å, and β= 114.47(2)°. The molecular structure has been elucidated by the analysis of 5 106
