Abstract

<abstract abstract-type="normal"> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>The Ba_2.64Ta_11.25O_30.81was prepared by conventional solid-state reaction technique as a single phase. It was found that the compound crystallizes in the tetragonal system, space group <italic>P</italic>4/<italic>mbm</italic> (No. 127) and unit-cell parameters are <italic>a</italic> = 12.508 59(8) Å, <italic>c</italic> = 3.912 81(2) Å, <italic>V</italic> = 612.218(7) ų, and <italic>Z</italic> = 1. The crystal structure of the Ba_2.64Ta_11.25O_30.81 phase is found to be closely related to the tetragonal tungsten bronze structure type, comprising interstitial (TaO)⁺ inclusions. Reference data were derived from the Rietveld analysis and reported here.</p> </abstract>
