  Convenient access to nitridosilicates with the whole range of dimensionality known for silicates is provided by synthesis in molten lithium in welded‐shut tantalum ampoules. For example, Li4Ca3Si2N6 consists of edge‐sharing “bow‐tie” [Si2N6]10− units, LiCa3Si2N5 has an edge‐sharing double‐chain and channels occupied by Li+ ions, and Li2Sr4Si4N8O exhibits a zeolite‐analogous structure due to inclusion

  Single-phase Eu2Si5N8 was synthesized from metallic europium and silicon diimide in a tungsten crucible using a big h frequency furnace. The Eu2Si5N8 structure consists of a three-dimensional network of corner sharing SiN4 tetrahedra in which the europium ions occupy two crystallographically different sites. Magnetic susceptibility measurements of Eu2Si5N8 show Curie-Weiss behaviour above 50 K with an experimental magnetic moment of 7.67(5)mu(B)/Eu, indicating divalent europium. Ferromagnetic ordering is detected at 13.0(5) K. The saturation magnetic moment is 7.0(1)mu(B)/Eu at 5 T and 4.5 K. The two europium sites could not be distinguished by Eu-151 Mossbauer spectroscopy. The room temperature spectrum could be fitted by only one signal at an isomer shift of delta = -11.82(5) mm/s subject to quadrupole splitting of DeltaE(Q) = 16.8(2) mm/s and an asymmetry parameter of 0.67(7). At 4.2 K full magnetic hyperfine field splitting is observed with a hyperfine field of 24.9(2) T at the europium nuclei. (C) 2002 Elsevier Science Ltd. All rights reserved.
• <i>RE</i>₄Ba₂[Si₁₂O₂N₁₆C₃]:Eu²⁺ (<i>RE</i> = Lu, Y): Green-Yellow Emitting Oxonitridocarbidosilicates with a Highly Condensed Network Structure Unraveled through Synchrotron Microdiffraction

  The oxonitridocarbidosilicates RE4Ba2[Si12O2N16C3]:Eu2+ (RE = Lu, Y) were synthesized by carbothermal reactions starting from RE2O3, graphite, Ba2Si5N8, Si(NH)(2), and Eu2O3. The crystal structure of Lu4Ba2[Si12O2N16C3]:Eu2+ was elucidated on a submicron-sized single crystal by a combination of transmission electron microscopy and microfocused synchrotron radiation. The compound crystallizes in trigonal space group P3 (no. 143) with a = 16.297(4) angstrom, c = 6.001(2) angstrom, and Z = 3 (R1 = 0.0332, wR2 = 0.0834, GoF = 1.034). According to Rietveld refinements on powder X-ray diffraction data, Y4Ba2[Si12O2Ni6C3]:Eu2+ is isotypic with a = 16.41190(6) angstrom and c = 6.03909(3) angstrom. The crystal structures are built up of vertex-sharing SiC(O/N)(3) tetrahedra forming star-shaped units [C-[4](Si(O/N)(3))(4)] with carbon atoms in fourfold bridging positions. Energy-dispersive X-ray spectroscopy and to the sum formula, lattice energy, and charge distribution calculations support the assignment of O/N/C atoms. When excited with UV to blue light, Eu2+-doped samples show green luminescence for RE = Lu (lambda(em) approximate to 538 nm, full width at half-maximum (fwhm) approximate to 3600 cm(-1)) and yellow emission in the case of RE = Y (lambda(em) approximate to 556 nm, fwhm 4085 cm(-1)).
