The molecular structure of the title AgI complex, [Ag(NO3)(C19H17P)2] or [Ag{(p-CH3C6H4)(C6H5)2P-κP}2-NO3-κ2O:O′], is described, where a distorted trigonal–planar coordination environment is exhibited about the central AgI atom; in this description, the two O atoms are assumed to occupy one position in the coordination sphere. The compound crystallized with half a molecule in the asymmetric unit having the AgI atom lying on a twofold axis.
