摘要：

The crystallographic data of CeFeSi-type RTX compounds have been refined from single crystal X-ray data. The results show that the atomic coordinates vary with the size of the rare earth element in order to keep optimum values for the T-X and R-X distances on one hand, and with the nature of the transition metal as a function of the relative T-R affinity on the other hand. These behaviours are compared with those observed in the closely related ThCr2Si2-type RT2X2 compounds. Attempts to correlate these results with the magnetic behaviours observed in the RTX and RT2X2 series are made. (C) 1998 Elsevier Science S.A.
