Crystal structure of bis­(13-di­meth­oxy­imidazolin-2-yl­idene)silver(I) hexa­fluorido­phosphate N-heterocyclic carbene (NHC) complex

摘要

The title salt, [Ag(C5H8N2O2)2]PF6, was obtained by deprotonation and metalation of 1,3-di­meth­oxy­imidazolium hexa­fluorido­phosphate using silver(I) oxide in methanol. The C—Ag—C angle in the cation is 178.1 (2)°, and the N—C—N angles are 101.1 (4) and 100.5 (4)°. The meth­oxy groups adopt an anti conformation. In the crystal, anions (A) are sandwiched between cations (C) in a layered arrangement {C…A…C}n stacked along [001]. Within a C…A…C layer, the hexafluoridophosphate anions accept several C—H⋯F hydrogen bonds from the cationic complex.
