摘要

The new compound Ce3Ni2(BN)(2)N was synthesized by a modified solid state metathesis reaction. The crystal structure of Ce3Ni2(BN)(2)N was found to be isotypic with the superconducting compound La3Ni2(BN)(2)N, according to Rietveld refinements performed on X-ray powder data (14/mmm, Z = 2, a = 3.5817(1) angstrom, c = 20.283(1) angstrom). Corresponding solid state reactions of mixtures composed of CeN/NiB and CeNi/BN yielded CeNi(BN) and a mixture of the two closely related layered structures (CeNi(BN))(2)(CeN)(x) with x = 0 and 1. Magnetization experiments on these samples revealed temperature independent paramagnetic behavior for Ce3Ni2(BN)(2)N and CeNi(BN) without any magnetic ordering down to 5 K.
