Single-crystal studies of an Mn5Si3-type phase in the Cr-Fe-Nb-Si quaternary system
A new quaternary compound Cr5−x−yFexNbySi3 has been studied using single-crystal X-ray diffraction data and electron microprobe analysis. The crystal structure was determined to be the same as that of the Mn5Si3 structure type: space group and Z = 2, a = 7.002(1), , Dx = 6.106 Mg m−3, μ(MoKα) = 15.03 mm−1, F(000) = 345, T = 293 K. R = 0.055 for 118 contributing unique reflections.
