| dc.description.abstractEn | The NaCdVO<sub>4</sub>–Cd<sub>3</sub>V<sub>2</sub>O<sub>8</sub> and CdO–V<sub>2</sub>O<sub>5</sub> sections of the ternary system Na<sub>2</sub>O–CdO–V<sub>2</sub>O<sub>5</sub> have been studied and the crystal structures of Cd<sub>3</sub>V<sub>2</sub>O<sub>8</sub> and Cd<sub>18</sub>V<sub>8</sub>O<sub>38</sub> compounds were determined from single-crystal X-ray diffraction data. Cd<sub>3</sub>V<sub>2</sub>O<sub>8</sub> crystallizes with the maricite-type structure in space group <i>Pnma</i>, <i>a</i>=9.8133(10) Å, <i>b</i>=6.9882(10) Å, <i>c</i>=5.3251(10) Å and <i>Z</i>=4, whereas Cd<sub>18</sub>V<sub>8</sub>O<sub>38</sub> crystallizes in space group <i>P</i>1 with a new-type structure, <i>a</i>=8.5761(14), <i>b</i>=8.607(3), <i>c</i>=12.896(2) Å, <i>α</i>=95.64(1), <i>β</i>=102.45(1), <i>γ</i>=108.42(1)° and <i>Z</i>=1. The Cd<sub>3</sub>V<sub>2</sub>O<sub>8</sub> structure is made up of Cd1O<sub>4</sub> infinite chains of edge-sharing Cd1O<sub>6</sub> octahedra which are parallel to the <i>b</i> direction. The Cd1O<sub>4</sub> chains are linked together by VO<sub>4</sub> tetrahedra and strongly distorted Cd2O<sub>4</sub> tetrahedra. The structure of Cd<sub>18</sub>V<sub>8</sub>O<sub>38</sub> is based on an ordered three-dimensional framework of cadmium and vanadium polyhedra that share corners. The distorted CdO<sub>6</sub> octahedra, CdO<sub>5</sub> trigonal bipyramids and CdO<sub>5</sub> square pyramids share corners, edges or faces. | |
