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

The structure of the title compound, [C14 H18 N2 )2 Ag2 ](NO3 )2 , 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. A nitrate group bonds with one of its O atoms to the first silver and uses the same oxygen to bond to a silver atom (related by symmetry to the second), thereby forming an extended network. The second nitrate group on the other silver bonds via two nitrate O atoms; one silver cation therefore has a coordination number of three whereas the second has a coordination number of four. One of the quinoxaline ligands has a disordered ethyl group.
