Synthesis and Molecular Structure of (3-(PPh3)-3,3-(NO3)-3,1,2-RhC2B9H11), a Versatile Metallocarborane Reagent.

摘要

The action of nitric acid or N02/N204 mixture on (3,3-(PPh3)2-3-H-3,1,2-RhC2B9H11) affords the nitratorhodacarborane (3-(PPh )-3,3-(N03)-3,1,2-RhC2B9H11) (I) whose structure has been determined by X-ray crystallography, triclinic, space group Pl, a= 12.592(5), b = 16.382(8), c = 17.059(6) degrees A, alpha = 75.74(4) (0) degrees, Beta = 105.34(3) (0) degrees, Gamma = 120.05(3) (0) degrees, Zeta = 2. The latter species has been shown to be a useful precursor in the synthesis of other rhodacarborane derivatives. (Author)
