摘要：

The structural data of several nickel-rich rare earth-nickel phases are reported. Excepting CeNi3, the other LnNi3-phases crystallize with the PuNi3-type structure. Both the Ce2Ni7- and Gd2Co7-type structures occur in several Ln2Ni7-phases. Ce2Ni7 possesses only the Ce2Ni7-type structure. Three modifications are encountered for Nd2Ni7. The low-temperature form is of the Ce2Ni7-type. The high-temperature forms are found to possess large periodicities along the c0-direction. Nd2Ni17 has the Th2Ni17-type structure at high temperatures. © 1969.
