Li<sub>2</sub>Ba<sub>4</sub>Al<sub>2</sub>Ta<sub>2</sub>N<sub>8</sub>O, the First Barium Nitridoalumotantalate with BCT‐Zeolite Type Structure
Abstract
<jats:title>Abstract</jats:title><jats:p>Single‐crystals of Li<jats:sub>2</jats:sub>Ba<jats:sub>4</jats:sub>Al<jats:sub>2</jats:sub>Ta<jats:sub>2</jats:sub>N<jats:sub>8</jats:sub>O:Eu<jats:sup>2+</jats:sup> were synthesized from Ba<jats:sub>3</jats:sub>N<jats:sub>2</jats:sub>, Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>, Li<jats:sub>3</jats:sub>N, Eu<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>, and lithium metal by a high‐temperature solid‐state reaction in a weld shut tantalum ampule. The crystal structure of Li<jats:sub>2</jats:sub>Ba<jats:sub>4</jats:sub>Al<jats:sub>2</jats:sub>Ta<jats:sub>2</jats:sub>N<jats:sub>8</jats:sub>O was determined by single‐crystal X‐ray diffraction and it crystallizes in the orthorhombic space group <jats:italic>Pnnm</jats:italic> (no. 58) with the lattice parameters <jats:italic>a</jats:italic>=1006.71(3), <jats:italic>b</jats:italic>=1026.58(3), <jats:italic>c</jats:italic>=607.10(2) pm, and a volume of <jats:italic>V</jats:italic>=0.62742(3) nm<jats:sup>3</jats:sup>. The compound is built up from AlN<jats:sub>4</jats:sub> and TaN<jats:sub>4</jats:sub> tetrahedra, which form a three‐dimensional network corresponding to the BCT‐zeolite type structure. Li<jats:sub>2</jats:sub>Ba<jats:sub>4</jats:sub>Al<jats:sub>2</jats:sub>Ta<jats:sub>2</jats:sub>N<jats:sub>8</jats:sub>O is homeotypic to Li<jats:sub>2</jats:sub>Sr<jats:sub>4</jats:sub>Si<jats:sub>4</jats:sub>N<jats:sub>8</jats:sub>O and Li<jats:sub>2</jats:sub>Sr<jats:sub>4</jats:sub>Al<jats:sub>2</jats:sub>Ta<jats:sub>2</jats:sub>N<jats:sub>8</jats:sub>O but, additionally, it could be successfully doped with the activator ion Eu<jats:sup>2+</jats:sup> and hence features an experimental observed overall emission at λ<jats:sub>max</jats:sub>=565 nm (fwhm=89 nm) consisting of a superposition of two adjusted emission bands at λ<jats:sub>max</jats:sub>=557 nm (fwhm=69 nm) and at λ<jats:sub>max</jats:sub>=604 nm (fwhm=102 nm).</jats:p>
