Abstract
Silver compound Ag2(Phtz)4](ReO4)2 (I) (Phtz is phthalazine, C8H6N2) is synthesized, and its crystal structure is determined. The crystals are triclinic: space group \(P\bar 1\), a = 9.651(2), b = 9.655(2), c = 10.884(2) A, α = 115.752(2)°, β = 94.582(2)°, γ = 106.000(2)°, V = 854.3(2) A3, Z = 1, ρcalcd = 2.404 g/cm3. The Ag atom forms a triangular coordination mode (Ag(1)-N(11) 2.34(2), Ag(1)-N(12A) 2.24(2), and Ag(1)-N(21) 2.28(1) A) by the nitrogen atoms of one monodentate and two bridging phthalazine molecules. Their interaction results in the formation of an almost planar centrosymmetric binuclear cationic complex [Ag2(Phtz)4]2+ (Ag(1)⋯Ag(1A) 3.452(7) A). The oxygen atoms of the ReO4− anion are randomly disordered over three positions each. The luminescence spectrum contains an emission band in the green region.
