Abstract—The silver complex with phenazine [Ag(Phz)₂(H₂O)]ReO₄ (Phz is C₁₂H₈N₂) has been synthesized,
and its crystal structure has been determined. The crystals are triclinic: space group a = 9.587(1) Å,
b=10.875(1) Å, c = 11.668(1) Å, = 104.98(1), = 103.87(1), = 92.94(1), V = 1132.6(2) ų, Z = 2, _calc
= 2.160 g/cm³. The structure is composed of the [Ag(Phz)₂(H₂O)]⁺ silver cationic complexes and anions.
The Ag⁺ ion is coordinated by two nitrogen atoms of independent phenazine molecules and the water oxygen
atoms and has a T-shaped coordination (Ag–N_av 2.223 Å, Ag–O_w 2.498(8) Å). Phenazine, being an electron-
donor ligand, forms columns due to – stacking interaction between the aromatic groups. The water molecules
form hydrogen bonds with the oxygen atoms of water molecules of neighboring complexes and with oxygen
atoms of the anions.
