Complexes of rhodium(III) with N-functionalized calix[4]resorcinolol
摘要:
Singularities of the rhodium trichloride reaction with calix[4]resorcinol functionalized with CH2N center dot (CH3)(2) groups in ethanol on the upper rim of the molecule, and also of calix[4]resorcinol with ethanol solution of rhodium trichloride saturated with nitrogen monoxide were studied. Neutral complex compounds separated in the solid form were characterized by IR spectroscopy, Raman spectroscopy, H-1 NMR, ESR, X-ray electron spectroscopy, electronic spectroscopy, and conductometry. Quantum-chemical calculations were performed on the basis of the density functional method in order to determine the geometric structure and energy characteristics of the complex compound and the zwitter-ion form of the ligand.

A supramolecular neutral complex was isolated in the solid state in the reaction of calix[4]-resorcinol having nitrogen-containing substituents [CH2N(CH3)(2)] on the upper rim of the molecule with RhCl3 center dot 3H(2)O in acetone. The complex, in addition to the calixarene structure and the rhodium-containing fragment, includes the dioxygen molecules bound to the rhodium ion [Rh+3(O (2) (-) )]. The compound was characterized by IR, Raman, H-1 NMR, ESR and electron spectroscopy, and by conductivity. The composition was confirmed by elemental analysis, XRD study and derivatography. The electronic structure of the complex was revealed by analysis of electron spin resonance spectrum and electron absorption spectrum.
