Cd. -The title compound is prepared from the elements (Ta containers, 900 C, 12 h; annealing at 600 C for 4 d). Ca 2 Pt 2 Cd crystallizes in the orthorhombic space group Immm with Z = 2 (single crystal XRD). The structure contains infinite, planar networks of [Pt 2 Cd] 4-groups, which can be described as tessellation of six-and four-membered rings of the anions. The Ca 2+ cations are located between the anionic layers. The Pt chains show a substantial long-short distortion of 0.52 Å. LMTO-ASA calculations reveal that the new compound is metallic in nature, and the overall bond populations are dominated by Ca-Pt bonds. -(SAMAL, S. L.; CORBETT*, J. D.; Z. Anorg. Allg. Chem. 638 (2012Chem. 638 ( ) 12-13, 1963Chem. 638 ( -1969 7-Double-Chain. -The title compound is prepared by reaction of Ca with Si(NH) 2 and Li 3 N using Li as a flux (sealed Ta ampule, 900 C, 12 h). The compound crystallizes in the monoclinic space group C2/c with Z = 8 (single crystal XRD). The structure contains [Si 2 ] double chains of corner-and edge-sharing SiN 4 tetrahedra. The Li atoms are situated in strands along the crystallographic b axis. The compound is further characterized by 29 Si and 7 Li MAS NMR spectroscopy. -(LUPART, S.; SCHNICK*, W.; Z. Anorg. Allg. Chem. 638 (2012) 12-13, 2015-2019, http -Yellow single crystals of the title compound are prepared by solid state reaction of a stoichiometric mixture of anhydrous Na 2 Se, Sb, and Se in a 3:2:3 ratio (evacuated silica ampule, 723 K, 10 weeks). Na 3 SbSe 3 crystallizes in the cubic space group P2 1 3 with Z = 4 (single crystal XRD). The structure contains trigonal SbSe 3 pyramids, which act as mono-, bi-, and tridentate ligands to sodium. There are three different Na sites, which are all coordinated by six Se atoms, providing a strongly distorted octahedral environment. NaSe 6 octahedra of identical type share common vertices. Na 3 SbSe 3 exhibits temperature dependent Na + conductivity above 380 K. The compound is further characterized by Raman spectroscopy. -(POMPE, C.; PFITZNER*, A.; Z. Anorg. Allg. Chem. 638 (2012) (1200 C, 8 h) and characterized by powder XRD and photoluminescence spectroscopy. Excitation and reflectance spectra of this phosphor show broad band excitation and absorption in the 240-470 nm near UV region, indicating its potential application in near UV diode based white-light LEDs. With the optimal Eu 2+ doping concentration of 0.01 mol, the phosphor exhibits strong yellow emission centered at 512 and 606 nm. It may have potential applications as a yellow-emitting near UV convertible phosphor in fabricating warm white-light LEDs with excellent color rendering index. 3 , Ta 2 O 5 , and Na 2 C 2 O 4 using urea as complexing agent and fuel (600 C, 4 h). The band gaps of the Bi 2 O 3 /Bi-NaTaO 3 samples can be tuned to effectively absorb visible light and induce visible light photocatalytic activity by varying the bismuth concentration. Photoluminescence studies confirm that the optimum amount of Bi effectively suppresses the recombination rate of...
