Series of Lanthanide-Mercury Compounds with Three-Dimensional Structures: Rational Preparation, Structures and Properties.

Three novel Ln-Hg complexes [Ln(HO)(μ-IA)HgBr] (Ln = Pr (1), Nd (2), and Er (3); HIA is isonicotinic acid) are synthesized and characterized. They feature three-dimensional (3-D) motifs. Solid-state UV/vis diffuse reflectance spectroscopy found that their band gaps are 4.
