Determination of the mutual orientation of the ligand molecule and the coordinating ion in paramagnetic complexes: Determination of the mutual orientation of the ligand molecule and the coordinating ion in paramagnetic complexes. Keiko, V. V.; Voronov, V. K. (Irkutsk. Inst. Org. Khim., Irkutsk, USSR). Izv. Sib. Otd.In this article, certain chemicals are used. Some of their cas registry numbers are 15492-52-1 and 17631-68-4 Akad. Nauk SSSR, Ser. Khim. Nauk, (6), 125-6 (Russian) 1976. CODEN: IZSKAB. DOCUMENT TYPE: Journal CA Section: 73 (Spectra by Absorption, Emission, Reflection, or Magnetic Resonance, and Other Optical Properties) A method is proposed which uses the magnetic dipole-dipole concept to describe the induced shifts and the mutual orientation of the paramagnetic atom and the ligand mol. The method consists in the minimization of the conformity criterion of measured and calcd. induced shifts. In the 1H NMR spectra of pyridine, the shifts induced by paramagnetic shift reagents do not involve a contact mechanism. The lanthanide-N distance calcd. for pyridine-lanthanide diketonate complexes in soln. using the induced shift values is approx. that in the cryst. complex. .
