A lanthanum coordination polymer with 3,6-dichlorophthalate and 2,4-dichloro-6-(ethoxycarbonyl)benzoate as ligands
A one-dimensional lanthanum-based coordination polymer based on 3,6-di-chloro-phthalate has been prepared and structurally described, namely, poly[[tetra-aqua-[2,4-di-chloro-6-(eth-oxy-carbon-yl)benzoato](μ<sub>3</sub>-3,6-di-chloro-phthal-ato)lanthanum(III)] monohydrate], {[La(C<sub>8</sub>H<sub>2</sub>Cl<sub>2</sub>O<sub>4</sub>)(C<sub>10</sub>H<sub>7</sub>Cl<sub>2</sub>O<sub>4</sub>)(H<sub>2</sub>O)<sub>4</sub>]·H<sub>2</sub>O}<sub>∞</sub>. Its crystal structure can be described based on mol-ecular 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 inter-metallic distances. It is a pity that, to date, only a lanthanum-based compound has been obtained.
