A laboratory EXAFS system with a curved crystal has been developed. This apparatus consists of a usual X-ray tube, a spectrometer with a Johan-type curved crystal, and two proportional counters detecting the X-rays. The resolution and performance tests have been carried out and excellent spectra have been obtained for NiO. With this system, aqueous solutions of ammine and ethylenediamine nickel(II) salts have been studied. The spectra were analyzed by the curve-fitting method by reference to the spectra of appropriate crystals containing the corresponding complexes. The values obtained for the Ni–N distances are 2.12±0.01 Å. These values are very close to those of the corresponding complexes in crystals. |
