ABSTRACT: In the title salt co-crystal, [Ag(C(6)H(5)N(2)O)(C(6)H(6)N(2)O)]ClO(4)·[Ag(C(6)H(6)N(2)O)(2)], the asymmetric unit comprises a [Ag(LH)(2)](+) cation, a perchlorate anion and a neutral (LH)AgL mol-ecule, where LH is pyridine-2-carboxaldoxime. Both silver-containing species feature N,N'-chelating LH and L ligands, which define an N(4) donor set that is highly distorted [dihedral angles between AgC(2)N(2) chelate rings = 45.7?(3) and 44.3?(2)°, respectively] owing, in part, to the close approach of a neighbouring Ag atom, leading to an argentophilic inter-action [Ag?Ag = 3.1868?(11)?Å]. The mol-ecular conformations are stabilized by intra-molecular O-H?O hydrogen bonds. In the crystal, O-H?O inter-actions lead to supra-molecular chains along [010]. Chains aggregate into layers in the ab plane, defining channels along [100] in which reside the perchlorate anions; the latter are disordered over two overlapped orientations in a 50:50 ratio.
