Abstract: The title compound, [Ni(C₁₂H₈N₂)₃]₂[Ag(CN)₂]₃(NO₃)·4.2H₂O, crystallizes with two independent [Ni(phen)₃]²⁺ cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N₆ donor sets), three near-linear [Ag(CN)₂]^- anions, one nitrate anion (N site symmetry 3) and 4.2 water molecules of crystallization, some of which are disordered. The [Ag(CN)₂]^- anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)₃]²⁺ cations. Some short C-HO and C-HN interactions may help to establish the packing.
