The title AgI complex, [Ag(NO2)(C19H17P)2], reveals a distorted pseudo-trigonal–planar shape around the AgI atom geometry resulting from the coordination of two phosphine ligands, as well as a nitrito-O,O′ ligand coordinating to the silver(I) atom through the oxygen atoms; in this description, the two oxygen atoms are assumed to occupy one position, forming an acute O—Ag—O angle of 51.44 (9)°. The plane resulting from the NO2 coordination to Ag is nearly perpendicular to the plane from the coordination of the phosphine-P atoms to Ag [dihedral angle = 86.43 (9)°].
