  Tetracalcium trimagnesium tetradecahydride, Ca4Mg3H14: the first ternary alkaline earth hydride

  摘要：

  The title compound and its deuteride, Ca4Mg3D14, were prepared from CaMg alloy at 410(10) degrees-C (deuteride: 458(8) degrees-C) under 53(3) bar hydrogen (95(5) bar deuterium) pressure and characterized by X-ray and neutron powder diffraction. The compound crystallizes with a new hexagonal structure type (space group P62mBAR (No. 189); lattice parameters at 20 degrees-C: a = 6.3056(2) angstrom, c = 6.8820(2) angstrom (hydride), a = 6.2902(2) angstrom, c = 6.8540(3) angstrom (deuteride), Z = 1) which contains an ordered array of four symmetry-independent deuterium atoms having respectively tetrahedral (D1: [3Ca, 1Mg]; D2: [4Ca]), trigonal bipyramidal (D3: [2Ca, 3Mg]) and triangular (D4: [3Mg]) metal coordinations. The metal-deuterium bond distances range from 1.85 to 2.44 angstrom (Mg-D) and from 2.29 to 2.48 angstrom (Ca-D).

• Effect of dealloying rate on transformation behavior during liquid metal dealloying
  作者：Soo-Hyun Joo、Hidemi Kato

  日期：2020.8

  Abstract Liquid metal dealloying is a new process that can be applied to synthesize non-noble porous materials by preventing oxidation in a utilized metallic melt. The effect of dealloying rate was investigated by electron backscattered diffraction at the reaction layer at various temperatures (600–800 °C) using (FeCo)xNi100−x precursors in a Mg melt. FeCo ligaments transformed via different mechanisms

  摘要 液态金属脱合金是一种通过防止金属熔体氧化来合成非贵金属多孔材料的新工艺。脱合金率的影响通过在不同温度（600-800°C）下使用 (FeCo)xNi100-x 前驱体在 Mg 熔体中在反应层的电子背散射衍射进行研究。根据脱合金速率、温度和 Ni 浓度，FeCo 韧带通过不同的机制转变。在前体表面附近的初始阶段，随机纹理在所有情况下都占主导地位。当脱合金速率在 600 ℃ 和 800 ℃ 减慢时，母体面心立方晶粒结构发挥了重要作用。第二阶段因脱合金条件而异，包括形成//法向纤维纹理或未知的特定取向关系。第三阶段的取向关系也有所不同。在 800 ℃时，脱合金速率应比 600 ℃ 慢得多，以出现特定取向关系的第三阶段。

  日期：1992.12

  Ca4Mg4Fe3H22 and its deuteride were synthesized by reaction of binary CaMg with iron wire at 500-530-degrees-C and 100-155 bar hydrogen (deuterium) pressure. The cubic structure was established from X-ray single-crystal and neutron powder diffraction: space group P43mBAR, a = 6.7151(6) angstrom (hydride) and 6.7016(4) angstrom (deuteride) at 295 K. It contains three types of deuterium atoms: two surrounding iron octahedrally with bond distances [Fe-4D1] = 1.583(3) angstrom and [Fe-2D2] = 1.562(5) angstrom, and one situated in a tetrahedral hole formed by one magnesium and three calcium atoms with bond distances [Mg-D3] = 1.808(7) angstrom and [Ca-D3] = 2.388(9) angstrom.

They crystallize with cubic symmetry, space group P (4) over bar 3m, Ca4Mg4Co3H19: a = 6.6953(2) Angstrom, deuteride: 6.6809(2) Angstrom; Yb4Mg4Co3H19: a = 6.6727(2) Angstrom, deuteride: 6.6591(1) Angstrom (T = 295 K). The structures contain tetrahedrally coordinated D- anions with bond distances [D3-Mg] = 1.912(5) Angstrom (Ca) and 1.902(7) Angstrom (Yb), [D3-3Ca)] = 2.355(6) Angstrom and [D3-3Yb] = 2.354(5) Angstrom, and square-pyramidal [CoD5](4-) complex anions in which the equatorial ligands are ordered with bond distances [Co-4D1] = 1.546(3) (Ca). 1.535(5) Angstrom (Yb) and the apical ligands are disordered with bond distances [Co-D2] = 1.586(9) (Ca), 1.60(1) Angstrom (Yb).
