The Absolute

Chiral compounds have played an important role in the development of coordination chemistry. Unlike organic chemistry, where mechanistic rules allowed the establishment of absolute configurations for numerous compounds once a single absolute determination had been made, coordination compounds are more complex. This article discusses the development of crystallographic methods and the interplay with coordination chemistry. Most importantly, the development of the Flack parameter is identified as providing a routine method for determining the absolute configuration of coordination compounds.

Triplet State Energy

A new family of lanthanide/boron-based complexes have been synthesized from the novel substituted poly(pyrazolylpyridyl)borate ligand containing phenyl substituents on the boron atom Ph2Bppy (L). The complexes have been fully characterized by analytical and spectroscopic methods. The single crystal X-ray structure and mass spectroscopy reveal the isostructural dinuclear complexes: [Ln2(L)2(NO3)2(OH)2] where Ln = Eu, Gd or Tb. Upon excitation of the Ln(III) complexes in DCM, their luminescence spectra display narrow f–f transitions. It is found that the ligand can efficiently sensitize the Tb(III) complex because of the better triplet state energy match to the Tb(III)–5D0 excited states.

Energetic Properties

Several new energetic coordination compounds (ECC) have been prepared using two 2-methyl-substituted tetrazoles. By simply changing the reaction conditions, the coordination sphere of the metal center can be manipulated in order to obtain different complexes with varying energetic properties.
