[Bis[μ-bis­(diphenyl­phosphino)methane-1:2κ²P:P′]-bis­(nitrito-κ²O,O′)]disilver(I) acetonitrile disolvate

The title complex, [Ag₂(NO₂)₂(C₂₅H₂₂P₂)₂]·2CH₃CN, is a centrosymmetric dimer in which two bis(diphenylphosphino)methane ligands bridge two Ag⁺ ions, forming an eight-membered ring with a short Ag...Ag separation of 3.1809 (5) Å. The distorted P₂O₂ coordination of the cation is completed by two O-donors from a symmetric bidentate chelate NO₂⁻ anion [Ag—O = 2.550 (3) and 2.567 (3) Å].

4,4′-Bipyridine–3,3′-disulfanediyl­bis­(1H-1,2,4-triazole-5-amine) (1/1)

In the title 1:1 adduct, C₁₀H₈N₂·C₄H₆N₈S₂·, the components are connected through N—H...N hydrogen bonds, leading to a two-dimensional structure. The C—S—S—C torsion angle is −83.6 (1)°. The dihedral angle between pyridine rings is 1.86 (15)°.
