- Abstract
New ternary compds. La3Pd25-xB8-y (x = 1.75, y = 0.07) and Ce3Pd25-xB8-y (x = 1.25, y = 2.00) have been synthesized by arc melting. Their crystal structures were detd. from X-ray single crystal diffraction data. Both compds. crystallize with a new monoclinic structure type, space group P21/c with a = 1.17567(2) nm, b = 1.05757(2) nm, c = 1.60664(3) nm, .beta. = 102.1788(10) deg, RF2 = 0.030 for 7427 structure factors and 289 variable parameters for La3Pd25-xB8-y and a = 1.17453(3) nm, b = 1.04571(3) nm, c = 1.59759(5) nm, .beta. = 102.132(2) deg, RF2 = 0.035 for 2805 structure factors and 283 variable parameters for Ce3Pd25-xB8-y. Rietveld refinement for the X-ray powder diffraction patterns for both compds. confirmed the structure models detd. from X-ray single crystal diffraction data.
