μ-Oxido-bis[hydridotris(trimethylphosphane-κP)iridium(III)](Ir—Ir) bis(tetrafluoridoborate) dihydrate
The title compound, [Ir(2)H(2)O(C(3)H(9)P)(6)](BF(4))(2)·2H(2)O, was isolated from the reaction between [Ir(COD)(PMe(3))(3)]BF(4) and H(2) in water (COD is cycloocta-1,5-diene). The asymmetric unit consists of one Ir(III) atom bonded to three PMe(3) groups, one hydride ligand and half an oxide liga...

Sumario: | The title compound, [Ir(2)H(2)O(C(3)H(9)P)(6)](BF(4))(2)·2H(2)O, was isolated from the reaction between [Ir(COD)(PMe(3))(3)]BF(4) and H(2) in water (COD is cycloocta-1,5-diene). The asymmetric unit consists of one Ir(III) atom bonded to three PMe(3) groups, one hydride ligand and half an oxide ligand, in addition to a BF(4) (−) counter-ion and one water molecule of hydration. The single oxide ligand bridging two Ir(III) atoms is disordered across an inversion center with each O atom having a 50% site occupancy. Each Ir(III) atom has three PMe(3) groups occupying facial positions, with the half-occupancy O atoms, a hydride ligand and an Ir—Ir bond completing the coordination sphere. The Ir—Ir distance is 2.8614 (12) Å, comparable to other iridium(III) metal–metal bonds. Two water molecules hydrogen bond to two BF(4) (−) anions in the unit cell. |
