Description

Crystal structure of SnZrF6 was determined by the method of X-ray diffraction analysis. The compound was prepared by slow crystallization from molten mixture of SnF2 and ZrF4 at mole ratio 2:1. Crystals of SnZrF6 are referred to monoclinic crystal system: a = 6.6119(5), b = 5.2503(5), c=6.9929(6) A, β = 114.239(4) deg, sp. gr. P2/n, Z = 2. The structure is a laminated one; the layer are formed by chains of Zr eight - cap species and Sn2+ cations bound by edges. Bond lengths Zr-F and Sn-F in the layer fall in the range 2.309(1)-2.269(1) and 2.186(1)-2.361(1) A respectively. The layer are bonded by Sn-F intermolecular bonds, their length being 2.868(1) and 2.871(1) A

Abstract (Russian)

Методом рентгеноструктурного анализа определена кристаллическая структура SnZrF6. Соединение получено медленной кристаллизацией из расплава смеси SnF2 и ZrF4 при мольном отношении 2:1. Кристаллы SnZrF6 относятся к моноклинной сингонии: а = 6.6119(5), b = 5.2503(5), с = 6.9929(6) А, β=114.239(4) град, пр. гр. Р2/n, Z = 2. Структура слоистая; слои образованы из связанных ребрами цепей Zr-восьмивершинников и катионов Sn2+. Длины связей Zr-F и Sn-F в слое находятся в пределах 2.309(1)-2.269(1) и 2.186(1)-2.361(1) А соответственно. Слои объединены межмолекулярными связями Sn-F длиной 2.868(1) и 2.871(1) А
