By means of solvothermal reactions, a novel lanthanide-mercury compound, {[Ho(IA)₃(H₃O)₂]_2n[2n(HgCl₄)][n(HgCl₅)]}·3nH₃O·nH₂O (1, HIA = isonicotinc acid) was prepared and structurally characterized by single-crystal X-ray diffraction. Complex 1 crystallizes in the C2/c space group of monoclinic system with a = 24.2147(5), b = 20.8106(4), c = 15.3060(3) Å, β = 128.326(2)°, V = 6050.8(2) Å³, C₃₆H₄₅Cl₁₃Hg₃Ho₂N₆O₂₀, M_r = 2274.26, Z = 4, D_c = 2.497 g/cm³, μ(MoKα) = 10.817 mm^–1 and F(000) = 4232. It exhibits a one-dimensional (1-D) chain-like structure. Solid-state photoluminescence measurement shows that it displays brown light emission bands. These emission bands originate from the characteristic emissions of the 4f electrons intrashell transitions of ⁵S₂ → ⁵I₈ and ⁵F₅ → ⁵I₈ of the holmium(Ⅲ) ions in 1. The photoluminescence emission energy transfer mechanism is elucidated by the energy level diagrams of the holmium(Ⅲ) ions and isonicotinic acid ligand. Complex 1 has CIE chromaticity coordinates of (0.4361, 0.4992). Solid-state UV/Vis diffuse reflectance spectra reveal that it possesses wide optical band gap of 4.94 eV.
