Abstract
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].

The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2
