A lanthanum coordination polymer with 3,6-dichlorophthalate and 2,4-dichloro-6-(ethoxycarbonyl)benzoate as ligands

Year: 2025

Type: article

Abstract: A one-dimensional lanthanum-based coordination polymer based on 3,6-dichlorophthalate has been prepared and structurally described, namely, poly[[tetraaqua[2,4-dichloro-6-(ethoxycarbonyl)benzoato](μ 3 -3,6-dichlorophthalato)lanthanum(III)] monohydrate], {[La(C 8 H 2 Cl 2 O 4 )(C 10 H 7 Cl 2 O 4 )(H 2 O) 4 ]·H 2 O} ∞ . Its crystal structure can be described based on molecular double chains in which lanthanum ions are linked to each other by ligands. There are several structural features that seem promising as far as luminescence properties are concerned, such as the presence of strong hydrogen bonds and of short halogen contacts, as well as quite long intermetallic distances. It is a pity that, to date, only a lanthanum-based compound has been obtained.
