Synthesis, structure and reactivity of a novel monocarbon hydridorhodacarborane closo-2,2-(ph3p)2-2-h-1-(me3n)-2,1 - rhcb10h10 molecular structure of 16-electron closo-2-(ph3p)-2-cl-1-(me3n)-2,1 - rhcb10h10

A novel 12-vertex monocarbon hydridorhodacarborane closo-2,2-(Ph3P)2-2-H-1-(Me3N)-2,1-RhCB10H10 1 has been synthesized by the reaction of Rh(PPh3)3Cl (2) with nido-B10H12CNMe3 (3) under alkaline conditions. At low temperature 1 exists as a mixture of two preferred conformers in solution, both having Cs symmetry, in accord with the hindered rotation of the (Ph3P)2RhH vertex with respect to the CB4 face of the monocarbon carborane cage. Complex 1 readily reacts with chlorine-containing reagents to form mononuclear 16-electron closo-2-(Ph3P)-2-Cl-1-(Me3N)-2,1-RhCB10H10 (5), whose structure was unambiguously confirmed by an X-ray diffraction study. The results of an X-ray diffraction study of the closely related dicarbon carborane derivative closo-3,3-(Ph3P)2-3-Cl-3,1,2-RhC2B9H11 (10), prepared from closo-3,3-(Ph3P)2-3-H-3,1,2-RhC2B9H11 by analogy with 5, are also reported.
