Zur Darstellung und Kristallstruktur des SrZnSb2 / On the Preparation and Crystal Structure of SrZnSb2

Abstract SrZnSb2 has been prepared and characterized analytically and structurally. The compound crystallizes in the orthorhombic system with a = 2305 ± 5 pm, b = 437 ± 1 pm, c = 446 ± 1 pm, Pnma-D2h16. Zn- and Sb-atoms form distorted fourfold pyramids, connected by common edges in the basis to two-dimensional sheets. These sheets are separated by double layers of Sr-atoms in which further Sb-atoms are located building four-cornered networks.
