Counter-anion role in the formation of two supra­molecular complexes: [Ag2(DPP)2](ClO4)2·CH3CN and [Ag2(DPP)2(NO3)2] {DPP is N-[(di­phenyl­phosphanyl)methyl]pyridin-4-amine}

Synopsis: In the Ag complex of N-[(di­phenyl­phosphanyl)methyl]pyridin-4-amine (DPP) with perchlorate, the unique Ag+ cation has a near-linear coordination geometry consisting of one pyridine N atom and one P atom from two different DPP ligands. In the analogous complex with nitrate, the nitrate anions weakly chelate to each Ag+ cation, leading to each Ag+ cation having a distorted tetra­hedral coordination geometry consisting of one pyridine N atom and one P atom from two different DPP ligands, and two chelating nitrate O atoms.

Formula: [Ag2(C18H17N2P)2](ClO4)2·C2H3N and [Ag2(C18H17N2P)2(NO3)2]
