Abstract
The crystal structure of Ce2Ni12P7 (Zr2Fe12P7 type) was determined from X-ray powder diffraction data: full profile refinement, hexagonal unit cell, space group P(6) over bar, a = 9.1008(4) angstrom, c = 3.7362(1) angstrom, R-B = 0.026, R-p = 0.055. The results of the magnetic and electrical resistivity measurements indicate a strong f-d hybridization of the 4f electrons of the cerium atom. Analysis of X-ray absorption spectroscopy experiments proved these findings, and the Ce valence in this compound was derived as v = 3.23-3.21 at 10 K and room temperature, respectively.
