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 $Pbar 1$ , a = 9.587(1) Å, b = 10.875(1) Å, c = 11.668(1) Å, α = 104.98(1)°, β = 103.87(1)°, γ = 92.94(1)°, V = 1132.6(2) Å3, Z = 2, ρcalc = 2.160 g/cm3. The structure is composed of the [Ag(Phz)2(H2O)]+ silver cationic complexes and ReO 4 ? 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-Nav 2.223 Å, Ag-Ow 2.498(8) Å). Phenazine, being an electron-donor ligand, forms columns due to π-π 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 ReO 4 ? anions. |
