Crystal structure of bis[1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene]silver(I) chloride tetrahydrofuran monosolvate
In the title salt, [Ag(C27H36N2)2]Cl·C4H8O, the AgI atom is coordinated by two 1,3-bis(2,6-dimethylphenyl)imidazol-2-ylidene ligands. The imidazole rings are inclined to one another by 46.69 (13)° and the benzene rings in each ligand are almost normal to the imdazole ring to which they are attached, with dihedral angles varying from 82.39 (13) to 88.27 (12)°. There are C—H...π interactions present in the cation, involving the two ligands, and the solvent molecule is linked to the cation via a C—H...O hydrogen bond. In the crystal, molecules are linked by trifurcated C—H...(Cl,Cl,Cl) hydrogen bonds, forming slabs parallel to (101). One isopropyl group is disordered over two sets of sites with an occupancy ratio of 0.447 (17):0.553 (17) and the THF molecule is disordered over two positions with an occupancy ratio of 0.589 (6):0.411 (6).
