Oxonium Derivative of Manganacarborane 1,1,1-(CO)3-6-C4H8O-isonido-1,2,4-MnC2B8H9

The reaction of the anionic complex [1,1,1-(CO)3-isonido-1,2,4-MnC2B8H10]–X+ (X = Na, PPN+, tmndH+) with THF in the presence of initiators (BF3·Et2O, H2SO4, AlCl3) leads to the formation of the neutral complex 1,1,1-(CO)3-6-C4H8O-isonido-1,2,4-MnC2B8H9 with a THF molecule at the boron atom in the B6 position of the carborane ligand. Structure of the complex was established by multinuclear NMR, IR spectroscopy, and elemental analysis methods.
