ABSTRACT

With triazole-modified derivative as link, one new framework [Cd₅ (μ₅ -HL^2-)₂(μ₄ -L^3-)₂(H₂O)₁₀]·2H₂O(1, H₃L = 2-(1,2,4-triazol-1-yl)benzene-1,3,5-tricarboxylic acid) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, powder X-ray diffraction and elemental analysis. Complex 1 exhibits a 3D (3,4,6)-connected net cross-linked by binuclear [Cd₂(COO)₅]^- cluster and mononuclear Cd(II) geometry via HL^2-/L^3- ligands. It crystallizes in triclinic system, space group P1^- with a = 7.7411(11), b = 9.8813(15), c = 20.177(3) Å, α = 85.547(4)°, β = 80.603(4)°, γ = 67.976(3)°, V = 1411.3(4) Å3 , Z = 1, Mr = 1876.89 g/mol, Dc = 2.208 mg/m³ , μ = 1.97 mm^-1, F(000) = 918, GOOF = 1.03, the final R = 0.0869 and wR = 0.1950 for 3127 observed reflections with I > 2σ(I). The solid photoluminescent behaviour of 1 has been further functionally investigated.
