Original Paper


A new Ag(I) complex Ag(HL)2(NO3) 1 has been synthesized with 3,5-diphenylpyrazole (HL) and characterized by IR spectrum, elemental analysis and X-ray crystallography. The crystallographic data for the complex 1: triclinic \( P{\bar{\text{1}}} \), a = 10.4369(17) Å, b = 10.4837(18) Å, c = 12.963(2) Å, α = 69.318(2)°, β = 86.733(3)°, γ = 88.263(2)°, V = 1324.7(4) Å3, Z = 2, Dc = 1.530 Mg m−3, F(000) = 620, μ = 0.803 mm−1, R 1 = 0.0251, wR 2 = 0.0638. Ag(I) atom is bound to two nitrogen atoms from two ligands. In solid state there are π···π interactions and C–H···π interactions between adjacent units to generate 2D supramolecular structure. The title complex shows strong luminescent emission at 389 and 467 nm in solid state at room temperature.

Graphical Abstract

A new silver complex has been synthesized with 3,5-diphenylpyrazole, in which π···π interactions and C–H···π interactions link the molecules to form two-dimensional supramolecular network.
