Bis{1,4-bis-[(3-butyl-imidazolium-1-yl)meth-yl]benzene}-silver(I) bis-(hexa-fluoridophosphate)
Abstract:
The asymmetric unit of the title complex, [Ag(2)(C(22)H(30)N(4))(2)](PF(6))(2), consists of one Ag(I) ion, one 1,4-bis-[(3-butyl-imidazolium-1-yl)meth-yl]benzene ligand and one discrete hexa-fluoridophosphate anion. The formula unit is generated by an inversion center. The unique Ag(I) ion is coordinated by two C atoms of two heterocyclic carbene ligands in an essentially linear geometry. In the crystal structure, cations and anions are linked through weak C-H⋯F hydrogen bonds, forming a three-dimensional network.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
