Boronic acid derivatized lanthanide-polyoxometalates with novel B-OH-Ln and B-O-Nb bridges
Abstract:
Three new boronic acid derivatized lanthanide-polyoxometalates (BA-Ln-POMs) were synthesized, in which boronic acids served as bi- or tri-dentate ligands and exhibited interesting coordination ability towards POMs and LnIII. The pH was found to be crucial in controlling the coordination modes of boronic acid and the formation of B-O-Ln and B-O-Nb bridges. Compared with the boronic acid-free Ln-POM, a longer lifetime was observed for compound 2Eu due to the coordination of boronic acids to the EuIII center.

A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...
