Poly[(μ-2,3-diethyl-7,8-di-methyl-quinoxaline-κ:)(2,3-diethyl-7,8-di-methyl-quinoxaline-κ)-μ-nitrato-κ:'-nitrato-κ,'-disilver(I)].

The structure of the title compound, [CHN)Ag](NO), contains subtle differences in ligand, metal, and counter-anion coordination. One quinoxaline ligand uses one of its quinoxaline N atoms to bond to one silver cation. That silver cation is bound to a second quinoxaline which, in turn, is bound to a second silver atom; thereby using both of its quinoxaline N atoms.

2,3-Di-ethyl-benzo[]quinoxaline.

The title compound, CHN, was synthesized by dispersing 3,4-hexa-nedione in a methanol-water solution containing the acid catalyst NHHF, then adding 1,2-di-aminona-phthalene. The fused-ring system of the title compound is close to planar (r.m.
