Bis[?-1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene-?N:N]silver(I) dinitrate dihydrate.

ABSTRACT: The reaction of 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) with silver(I) nitrate in a 1:1 molar ratio generates the metallacyclic title complex, [Ag(2)(C(12)H(14)N(4))(2)](NO(3))(2)·2H(2)O, in which the bib ligand displays a cis configuration. Each bib ligand acts as a bidentate bridging ligand connecting a pair of Ag(I) ions to form a [2 + 2] metallamacrocycle in which the Ag?Ag distance is 6.77?(2)?Å. Each Ag(I) ion has weak contacts (2.91?Å) with the nitrate anion. The uncoordinated water mol-ecules make hydrogen bonds with nitrate O atoms, forming chains. The H atoms attached to the uncoordinated nitro-gen inter-act with these chains through N-H?O hydrogen bonds, forming layers parallel to the (11) plane.
