Syntheses, structures, photoluminescence and semiconductor properties of two novel mercury-lanthanide complexes with a three-dimensional open framework

Preparation and characterization of two lanthanide complexes with one-dimensional chain-like structures

“…The asymmetric unit of compound 2 possesses one lutetium(III) ion, two mercury ions, seven chloride ions, two coordinating water molecules, and three isonicotinic acid ligands (Figure 1 3Å, which is normal and comparable with those found in the literature. [23][24][25] Every two neighboring lutetium(III) ions connect together through isonicotinic acid ligands to yield a 1D Lu-(IA) 2 -Lu-(IA) 4 -Lu-(IA) 2 chain, running along the c direction ( Figure 2). The Lu-(IA) 2 -Lu-(IA) 4 -Lu-(IA) 2 chains, HgCl 4 2− anions, HgCl 5…”

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

“…For the sake of seeking after interesting MOFs (metal–organic frameworks) with fascinating structure characteristics and useful performance, for many years we have devoted ourselves to the investigating field of Ln–IIB MOFs by way of different types of organic coodinating species. In this research field, we have reported two Ln–IIB chloride compounds before, and they show fascinating performance . In this context, we report preparation, structures and performance of three novel Ln–Hg complexes [Ln­(H 2 O) 2 (μ-IA) 3 Hg 3 Br 6 ] n (Ln = Pr ( 1 ), Nd ( 2 ), and Er ( 3 ); HIA is isonicotinic acid).…”
