title: [Bis[μ-bis-(diphenyl-phosphino)methane-1:2κ(2)P:P']-bis-(nitrito-κ(2)O,O')]disilver(I) acetonitrile disolvate.
abstract: The title complex, [Ag(2)(NO(2))(2)(C(25)H(22)P(2))(2)]·2CH(3)CN, 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 P(2)O(2) coordination of the cation is completed by two O-donors from a symmetric bidentate chelate NO(2) (-) anion [Ag-O = 2.550 (3) and 2.567 (3) Å].
