[(1,2,5,6-η)-Cyclo-octa-1,5-diene](1-ethyl-3-isopropyl-1,3-imidazol-2-yl-idene)(tri-phenyl-phosphane)rhodium(I) tetra-fluorido-borate.

ABSTRACT: A new N-heterocyclic cationic rhodium(I) complex with a tetra-fluorido-borate counter-anion, [Rh(C₈H₁₄N₂)(C₈H₁₂)(C₁₈H₁₅P)]BF₄, has been prepared and structurally characterized. The cationic complex exhibits a distorted square-planar environment around the rhodium(I) ion. Two connections are made from rhodium(I) to the carbon atom of an N-heterocylic carbene ligand and to the phospho-rus atom of a tri-phenyl-phosphane ligand. The remaining two coordination sites are made via a bidentate inter-action from the two olefinic bonds of cyclo-octa-diene to the rhodium(I) ion. The compound includes an out-sphere tetra-fluorido-borate counter-anion. Within the crystal of the compound exist several weak inter-molecular C-H⋯F inter-actions.

Project description:In the title compound, the iridium(I) atom has a distorted square-planar coordination environment. A new triazole-based N-heterocyclic cationic carbene iridium(I) complex with a tetrafluoridoborate counter-anion, [Ir(C8H12)(C7H13N3)(C18H15P)]BF4, has been synthesized and structurally characterized. The IrI atom of the cationic complex has an expected square-planar coordination environment with unexceptional bond lengths. There are several close F⋯H contacts between the cations and the anions in the range 2.36–2.58 Å, stabilizing the orientation of the out-sphere [BF4−] counter-anion. In the crystal, C—H⋯π(ring) interactions are observed that orient the phenyl rings of the triphenylphosphane ligands.

Project description:The cationic complex in the title salt, [Ir(C8H12)(C18H15P)(C10H11N3)]BF4, exhibits a distorted square-planar geometry around the IrI ion. A new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetrafluoridoborate counter-anion, [Ir(C10H11N3)(C8H12)(C18H15P)]BF4, has been synthesized and structurally characterized.

One significant non-standard hydrogen-bonding interaction exists between a hydrogen atom on the N-heterocyclic carbene ligand and a fluorine atom from the counter-ion, BF4−. In the crystal, π–π stacking interactions are observed between one of the phenyl rings and the triazole ring. Both intermolecular and intramolecular C—H⋯π(ring) interactions are also observed.

Project description:The RhI atom in the title compound has a distorted square-planar coordination environment, defined by a bidentate cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene and a chloride ligand with bromide substitutional disorder. A new triazole-based neutral RhI complex, [Rh(Cl0.846Br0.154)(C6H11N3)(C8H12)], has been synthesized and structurally characterized. The RhI atom has a distorted square-planar coordination environment, formed by a bidentate cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene and a halide ligand that shows substitutional disorder (Cl:Br = 0.846:0.154). No significant intermolecular interactions other than van der Waals forces are found in the crystal structure. Diffraction data indicated a two-component inversion twin with a ratio of 0.95 (5):0.05 (5).

[(1,2,5,6-η)-Cyclo-octa-1,5-diene]bis-(1-isopropyl-3-methyl-imidazolin-2-yl-idene)rhodium(I) tetra-fluorido-borate.

Project description:In the title compound, [Rh(C(8)H(12))(C(7)H(12)N(2))(2)]BF(4), the square-planar Rh complex cation and the BF(4) (-) anion are both bis-ected by a crystallographic twofold rotation axis. The Rh and B atoms lie on this axis and all others are in general positions. In the crystal, two unique C-H⋯F hydrogen-bonding inter-actions are present, which involve both imidazolin-2-yl-idene H atoms. They form two separate C(5) motifs, the combination of which is a rippled hydrogen-bonded sheet structure in the ab plane.

Project description:In the title complex, [Pt(C(6)H(11))Cl(C(8)H(12))], the Pt(II) ion lies in a distorted square-planar environment defined by the Cl and cyclo-hexyl C atoms and the mid-points of the two π-coordinated double bonds of cyclo-octa-1,5-diene. As a result of the different trans influences of the Cl atom and the cyclo-hexyl group, the Pt-C bonds trans to the cyclo-hexyl group are longer than those trans to the Cl atom.

Project description:A new, cationic N-heterocyclic carbene RhI complex with a tetra-fluorido-borate counter-anion, [Rh(C8H12)(C8H15N3)(C18H15P)]BF4, has been synthesized and structurally characterized. There are two independent ion pairs in the asymmetric unit. Each complex cation exhibits a distorted square-planar conformation around the RhI atom. Bond lengths and bond angles are as expected for an Rh-NHC complex. There are several close, non-standard C-H⋯F hydrogen-bonding inter-actions between the ions. One of the tetra-fluorido-borate anions shows statistical disorder of the F atoms.
