Synthesis, spectroscopic and structural characterization of cyclometallated rhodium(III) complexes with 1-phenyl-1H-pyrazole and α-diimines ligands, comparison with their iridium(III) analogues
The paper deals with the synthesis of a series of cationic [Rh(ppz)2(N^N)]+ complexes containing deprotonated 1-phenyl-1H-pyrazole as cyclometallating (C^N) ligands and α-diimines (2,2’-bipyridine, 1,10-phenanthroline and its derivatives) as ancillary (N^N) ligands in the form of salts with PF6− counter ions. These complexes were obtained from [(ppz)2Rh-μ-Cl]2 precursor through cleaving the μ-dichloro-bridged dimer with N^N ancillary ligands. The complexes were identified by means of NMR spectroscopy and MS spectrometry and their molecular structures were finally confirmed by X-ray crystallography. These complexes showed strong luminescence in MeOH/EtOH 1:1 glasses at 77 K but were very week or almost non-emitting species in MeCN solutions at room temperature. Their emission properties were compared to analogues Ir(III) complexes.
期刊介绍：
Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry.
We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
