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).
