A cationic rhodium(I) N-heterocyclic carbene complex isolated as an aqua adduct
Abstract
The title complex, aqua-[1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene] (η -cycloocta-1,5-diene)rhodium(I) tetrafluoridoborate, [Rh(C H )(C H N )(H O)]BF , exihibits a squareplanar geometry around the Rh(I) atom, formed by a bidentate cycloocta-1,5-diene (cod) ligand, an N-heterocylcic carbene and an aqua ligand. The complex is cationic and a BF anion balances the charge. The structure exists as a hydrogenbonded dimer in the solid state, formed via interactions between the aqua ligand H atoms and the BF F atoms. 4 - - 8 12 27 36 2 2 4 4 4
