  Synthesis and Structure of CsNaLa₆Br₁₄N₂ and La₃Br₆N:  Rare-Earth-Metal Nitride Halides with Isolated Bitetrahedral La₆N₂ Units

  摘要：

  The title compounds were obtained in high yields as pale yellow, transparent crystals after reacting appropriate mixtures of CsBr, NaBr, LaBr3, and LaN in sealed Ta tubing at 850 degrees C for 20 d. The structures have been established by single-crystal X-ray diffraction techniques and powder diffraction. CsNaLa6Br14N2 forms a new structure type in the monoclinic space group P2(1)/n with the lattice parameters a = 10.452(1) Angstrom, b = 13.193(2) Angstrom, c = 10.876(2) Angstrom, beta = 95.07(1)degrees, and Z = 2. La3Br6N is isotypic to Ce3Br6N and crystallizes in the orthorhombic space group Pbca with a = 11.212(1) Angstrom, b = 11.828(1) Angstrom, c 17.176(1) Angstrom, and Z = 4. The significant structural features of both compounds are pairs of rare-earth-metal tetrahedra that are each centered by N and share a common edge to form La6N2 bitetrahedral units. These are surrounded and interbridged by Br atoms to form a three-dimensional network. Ln the case of CsNaLa6Br14N2 the Cs and Na atoms are located in bromine-lined cuboctahedral and octahedral cavities, respectively. Although "normal-valent" salts, the structures of the new nitride halides are geometrically closely related to the metal-rich cluster compounds such as Cs2La10I17Co2 with bioctahedral La-10 units that are centered by the transition-metal atoms. Calculations of the Madelung part of lattice energy, MAPLE, illustrate the close relationship of the two structures.

  通过使LaN与Ca 3 N 2在1200至1300℃之间的温度反应，制备了La 1- x Ca x N 1- x / 3（0 < x <0.7）。所有相都具有类似LaN的岩盐结构，没有证据表明La和Ca之间或x / 3 N空位之间有序。根据维加德定律，具有不同组成的材料的晶格参数介于同构LaN和CaNH的晶格参数之间。Ca在标题化合物中采用八面体配位，与其在Ca 3 N 2中的四面体配位几何相反。这些材料导电不良。

  The compounds RENi(BN) with RE = Y, La, Ce, Pr, Tm and Yb were synthesized by solid state reactions from metal powders and α-BN at temperatures between 1000° and 1200 °C. In addition, the mixed phases (Ca,Yb)Ni(BN) and (Ca,Tm)Ni(BN) were synthesized. All products were characterized by powder XRD measurements and indexed isotypic with the structure of CaNi(BN), consistent with the tetragonal space group

  oxidenitrides BaCeLn(O,N)4 (Ln = La, Ce) have been synthesized by reaction of perovskite-type BaCeO3 with LnN at 800°C. X-ray powder diffraction and magnetic data are presented. Composition data for BaCeLn(O,N)4 and observed magnetic moments which are smaller than would be expected for only a Ce3+ electronic configuration suggest a mixed-valence state for cerium. Ca Ce2(O,N)4 and BaThCe(O,N)4 could not

  Abstract The reaction of several rare earth ( RE ) metals ( RE = Y, La, Ce, Pr, Eu, Gd, Tb and Lu) with gaseous hydrogen and the subsequent reaction of the resulting hydrides with nitrogen gas have been investigated by means of a combinatory approach of thermogravimetric and differential thermal analysis. Focus was laid on the fabrication of bulk material, in quantities suitable as precursor materials
