LiDy2Cl5, an Intermediate of the Metallothermic Reduction of DyCl3 with Lithium LiDy2Cl5 has been obtained via 2 Li + 2 DyCl3 = LiDy2Cl5 + LiCl as black single crystals (700°C, 1 week, sealed tantalum container) and crystallizes monoclinic with a = 1545.6(7), b = 659.2(2), c = 728.7(3) pm, β = 95.79(3)°, Z = 4, C2/c. Octahedra [LiCl6] are connected via common corners to rings [Li4Cl20], these parallel (100) to layers [LiCl4]. Bicapped trigonal prisms [DyCl8] are connected to a three-dimensional network [(DyCl13/3Cl23/3Cl32/4)] ? [Dy2Cl5]. 相似文献

HgPb2O2Cl2, a “Perforated” Lead(II) Oxide Single crystals of HgPb2O2Cl2 were grown in a HgCl2 flux by reaction of PbO with HgCl2. Crystal structure analysis by single crystal X-ray methods were carried out. HgPb2O2Cl2 crystallizes monoclinic with a = 11.788(2) Å, b = 3.910(1) Å, c = 7.749(2) Å, β = 122.64(3)°, space group C2/m (No. 12) and Z = 2. HgPb2O2Cl2 is the first member of a new structure type, closely related to the structure of PbO. 相似文献

In connection with the chemical aspects of his work „Farbenlehre”︁, which involved him almost his whole life, Goethe, too, performed chemicals experiments which he recorded so carefully that his notes can still he reproduced today. It deals with tests series on the reactions of metal salts solutions with yellow prussiate of potash (potassium ferrocyanide), at that time called „Berlinerblau Lauge”︁, acid-base reactions of numerous blossom dyes (today noted as anthocyanes), silver pigments and the coloured ions of manganese in its several oxidation states, called as mineral chameleon. 相似文献
