Copper N-(4′-benzo-15-crown-5)-2-(amino-N-tosyl)phenylaldiminate: Complexing and ion-selective properties
摘要:
Copper(II) chelate with N-(4'-benzo-15-crown-5)-2-(amino-N-tosyl)phenylaldiminate CuL2 and its coordination compounds with Li, Na, and K salts have been synthesized. Their IR spectra have been studied and assignment of the key vibration frequencies of CuL2 and complexes based on it. On the basis of spectral, thermogravimetric, and elemental analysis datasassumptions concerning the compound structure are made. The ion-selective properties of CuL2 are studied by potentiometry.

The ZnL2 complex (I) (HL = N-(4'-benzo-15-crown-5)-2-(amino-N-tosyl)phenylaldimine) is synthesized and studied by IR spectroscopy and X-ray diffraction analysis. The crystals are monoclinic: a = 23.139(2) angstrom. b = 19.931(2) angstrom, c = 14.604(2) angstrom. beta = 121.20(1)degrees. Z = 4. space group C2/c. R = 0.751 tor 766 reflections with l > 2 sigma(l). The Zn atom in a molecule of the complex lies on a twofold axis and is coordinated at the vertices of a distorted tetrahedron by four N atoms of two HL ligands (average Zn-N distance 2.024 angstrom).
