    Abstract:
    In the title salt, [Ag(C27H36N2)2]Cl·C4H8O, the Ag(I) atom is coordinated by two 1,3-bis-(2,6-di-methyl-phen-yl)imidazol-2-yl-idene 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 inter-actions present in the cation, involving the two ligands, and the solvent mol-ecule is linked to the cation via a C-H⋯O hydrogen bond. In the crystal, mol-ecules 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 mol-ecule is disordered over two positions with an occupancy ratio of 0.589 (6):0.411 (6).
