  RE4[P1-x(C2)x]3 (RE = La-Nd)：由磷和碳形成的混合阴离子亚结构 

  摘要：

  稀土磷化物碳化物 RE4[P1–x(C2)x]3 (RE = La, Ce, Pr, Nd) 代表了由磷和碳形成的混合阴离子亚结构的第一个例子，是形成的第一步混合无机 P-C 物种。晶体结构、磁性、XAS 数据和量子化学计算结果的特性证实了稀土阳离子 RE 和磷阴离子之间相互作用的离子性质，而 C2 阴离子的 π 态和 d（和/ 或 f) 指示了 RE 组件的状态。因此，尽管磷化物碳化物和磷化物硅化物之间有广泛的化学类比，但稳定结构基序的原子相互作用略有不同。

  relationships in the LnSiP3 (Ln = La and Ce) family of compounds are reported. An innovative synthetic method was developed to overcome differences in the reactivities of the rare-earth metal and refractory silicon with phosphorus. Reactions of atomically mixed Ln + Si with P allowed for selective control over the reaction outcomes resulting in targeted isolation of three new polymorphs of LaSiP3 and two

  The transformations caused by irradiation and thermal treatments of crystalline cerium (IV) phosphate CeP-E (Ce(NH/sub 4/PO/sub 4/)0.44(HPO/sub 4/)1.56), which has a high ion exchange capacity, have been studied by electron microscopy, infrared spectroscopy, and X-ray powder diffraction. Electron bombardment in the electron microscope transformed CeP-E into either hexagonal CePO/sub 4/ or a vitreous

• Phase transitions of lanthanide monophosphides with NaCl-type structure at high pressures

  Lanthanide monophosphides LnP (Ln = La, Ce, Pr, Nd, Sm, Gd, To, Tm and Yb) with a NaCl-type structure have systematically been prepared at high temperatures. Using synchrotron radiation, X-ray diffractions of LnP have been studied up to 61 GPa at room temperature. The NaCl-CsCl transition for CeP is found at around 25 GPa. First-order phase transitions of LnP (Ln = La, Pr and Nd) with the crystallographic change occur at around 24, 26 and 30 GPa, respectively. The structure of the high pressure phases of these phosphides is a body center tetragonal structure (Ln: 0, 0, 0; P: 1/2, 1/2, 1/2; space group P4/mmm), which can be seen as the distorted CsCl-type structure. The Pr-P distance in the high pressure form of PrP is 2.789 Angstrom. This almost agrees with the sum of covalent radii of Pr and P The Pr-P bond has the covalent character at very high pressures. Similar results are also obtained for LaP and NdP. The pressure-induced phase transitions of SmP, GdP, TbP, TmP and YbP occur at around 35, 40, 38, 53 and 51 GPa, respectively. The structure of the high pressure phase is unknown. The phase transitions of LnP with many f-electrons are not due to the mechanism of the ordinary NaCl-CsCl transition. The transition pressures of LnP increase with decreasing the lattice constants in the NaCl-type structure, which decrease with increasing atomic number of the lanthanide atoms.

• Ce₄(P_1-<i>_x</i>Si<i>_x</i>)_3-<i>_z</i>:  A First Example for the Stabilization of the Anti-Th₃P₄ Type Structure by Substitution in the Non-Metal Substructure

  A first rare-earth phosphide silicide Ce-4(P1-xSix)(3-z) and its analogues with La, Pr, and Nd were synthesized and characterized. The compounds crystallize in the anti-Th3P4 structure type. The cerium compound shows a mixed occupation of the 12 a site with Si and P and possesses a wide homogeneity range with respect to x and z variation. The electronic configuration of Ce, deduced from magnetic susceptibility and X-ray absorption spectroscopy data, remains 4f(1) (Ce3+) independently from x and z. The cerium valence and the phase stability region are discussed employing electronic band-structure calculation and chemical bonding analysis with electron localization function. Atomic interactions are shown to remain nearly unchanged, while the change of the excess electron concentration with P/Si substitution is considered to play the main role for the stabilization of the structural motif.
