Structural Studies and Photoluminescence of a Novel Mercury(Ⅱ) Complex Based on a Tris[4-(1-pyrazolyl)-phenyl]amine
A novel iodine-bridged mercury(Ⅱ) complex [Hg(L)(μ-I)(I)]2 was isolated by a reaction between HgI2 and the organic ligand tris[4-(1-pyrazolyl)phenyl]amine L, and the complex and ligand were both characterized by FT-IR spectroscopy, 1H NMR and elemental analysis. The complex crystallizes in monoclinic space group P21/c with a = 9.579(5), b = 27.331(5), c = 11.268(5) A, β = 105.624(5)°, Z = 2, Dc = 2.099 g·cm-3 and μ = 7.620 mm-1. The title complex C54H4>Hg2I4N14 is a diplex bridged dinuclear complex consisting of two Hg(Ⅱ) ions, two ligands, two bridging I-anions, and two terminal 1-anions. Universal hydrogen bonds in the complex with the partners of neighboring molecule have generated a supramolecular arrangement. Solid-state emission of the ligand and its complex have been investigated at room temperature.
