The reaction of the known closo-ruthenacarborane 3-H-3-Cl-3,3-(PPh3)2-closo-3,1,2-RuC2B9H11 with tridentate nitrogen-based bis(pyridylmethyl)amine ligands of the general formula (2-C5H4NCH2)2NR (R = H, Me, Et, iPr, tBu) in benzene solution at 60° allowed us to isolate novel ruthenacarborane clusters 3,3,3-[(2′-NC5H4CH2)2NR]-pseudocloso-3,1,2-RuC2B9H11. According to the performed X-ray study, the obtained compounds are the first examples of pseudocloso-metallacarboranes bearing unsubstituted C2B92-nido-carborane ligand. In spite of the determined pseudocloso structure of the complexes in the solid state, the recorded 11B{1H} NMR spectra indicate that some of them are converted into the closo isomers in solution The conducted quantum-chem. calculations have confirmed the subtle difference between two configurations and possible rearrangement in solution The performed electrochem. investigations show the ability of the formed ruthenacarboranes to undergo reversible oxidation to Ru(III) species. In the experiment, the researchers used Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0Category: pyridine-derivatives)
Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0) is a secondary amine with two picolyl substituents. The compound is a tridentate ligand in coordination chemistry and commonly used to produce Zn-based chemosensors/probes, such as Zinpry.Category: pyridine-derivatives
