摘要：

High temperature reactions led to single crystals of Ba2Er2Zn8O13. It crystallizes with orthorhombic symmetry, space group C2v(12)-Cmc2(1) a = 6.276, b = 10.871, c = 10.195 angstrom, Z = 2. The hitherto unknown crystal structure shows Zn2+ with tetrahedral, Er3+ octahedral and Ba2+ cuboctahedral coordination by O2-. It will be shown that parts of the [Zn8O13] network are fragments of the ZnO structure showing O2- within a tetrahedral zinc coordination. A deficit of two O2- ions per unit cell is focused on two point positions.
