Abstract

In this work, a method for the preparation of a new chelating ligand [B₁₂H₁₁NH(CH₂COOH)₂]– via the alkylation reaction of ammonio-closo-dodecaborate anion has been proposed. The product and its synthetic precursor were characterized by NMR and IR spectroscopy, ESI-mass spectrometry, and X-ray analysis of single crystals. Two heteroligand complexes of europium(III) [Eu(Phen)₂B₁₂H₁₁NH(CH₂COO)₂](H₂O)₄ and [(Eu(phen)(DMSO)₃)₂(µ-B₁₂H₁₁NH(CH₂COO)₂)₂] were prepared based on the boron-containing ligand. The analysis of crystal structures showed the presence of intra- and intermolecular dihydrogen bonds.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
