Syntheses, crystal structures and characterizations of BaZn(SeO3)2 and BaZn(TeO3)Cl2

Two new barium zinc selenite and tellurite, namely, BaZn(SeO3)2 and BaZn(TeO3)Cl2, have been synthesized by the solid state reaction. The structure of BaZn(SeO3)2 features double chains of [Zn(SeO3)2]2− anions composed of four- and eight-member rings which are alternatively along a-axis. The double chains of [Zn2(TeO3)2Cl3]3− anions in BaZn(TeO3)Cl2 are formed by Zn3Te3 rings in which each tellurite group connects with three ZnO3Cl tetrahedra. BaZn(SeO3)2 and BaZn(TeO3)Cl2 are wide bandgap semiconductors based on optical diffuse reflectance spectrum measurements.

Two new barium zinc selenite and tellurite, namely, BaZn(SeO3)2 and BaZn(TeO3)Cl2, have been synthesized by solid state reaction. The structure of BaZn(SeO3)2 features 1D double chains of [Zn(SeO3)2]2− anions composed of four- and eight-member rings which are alternatively along a-axis. The 1D double chains of [Zn2(TeO3)2Cl3]3− anions in BaZn(TeO3)Cl2 are formed by Zn3Te3 rings in which each tellurite group connects with one ZnO3Cl and two ZnO2Cl2 tetrahedra.
