Abstract

The reactions of o-carborane [P,P] ligand L1 with NiCl2(PPh3)2 and [IrCl(COD)]2 under an open atmosphere lead to two nido-carborane species 1 and 2 containing [O,P] or [O,O] ligands.All these complexes have been characterized by NMR,MS,IR and X-ray diffraction analyses.Complex 1 with solvent CHCl3 formed the normal Cl…H interaction and novel CH…π interaction.Complex 2 is the first Ir(Ⅰ) compound containing [O,P] o-carborane ligand.However,due to the difference of metal(Ni and Ir),the [P,P] ligand L1 was oxizided to novel [P,O] ligand and [O,O] ligand,respectively.CCDC: 927419,1;927420,2.
