Abstract:
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](μ3-3,6-di-chloro-phthal-ato)lanthanum(III)] monohydrate], {[La(C8H2Cl2O4)(C10H7Cl2O4)(H2O)4]·H2O}∞. 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.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Transition metals are found everywhere from vitamin supplements to electroplating baths. Transition metals also make up the pigments in many paints and compose all minerals. Typically, transition metals are found in the cationic form since they readily oxidize, or lose electrons, and are surrounded by electron donors called ligands. These ligands do not form ionic or covalent bonds with the metal...
