A New Strontium-Oxometallate: Sr9Zn4Cu2O14, Containing Sr2+ in Face Connected OctahedraSingle crystals of Sr9Zn4Cu2O14 were prepared in closed Cu-tubes. Modern X-ray investigations lead to monoclinic symmetry (space group C2h3—C2/m, a = 22.22; b = 3.61; c = 11.29; β = 98.6°; Z = 2). The crystal structure is characterized by a threedimensional Sr/O network, containing Sr2+ in octahedral and trigonal prismatic coordination. The SrO6 octahedra are partly face connected. Incorporated Zn2+ and Cu+ Ions show tetrahedral and dumbbell like coordination.
Notes:
In geschlossenen Cu-Rohren wurden Einkristalle von Sr9Zn4Cu2O14 dargestellt. Moderne Röntgenmethoden führen zu monokliner Symmetrie [Raumgruppe C2h3—C2/m; a = 22,22; b = 3,61; c = 11,29 Å; β = 98,6°, Z = 2]. Die Kristallstruktur enthält ein Sr/O-Gerüst mit Sr2+ in oktaedrischer und trigonal prismatischer Koordination. SrO6-Oktaeder treten partiell flächenverknüpft auf. In das Sr/O-Gerüst sind Zn2+-Ionen in Tetraederlücken und Cu+-Ionen mit hantelförmiger Koordination eingelagert.
