Abstract

Single crystals of Pr₂Te₄O₁₁ have been grown through the reaction of Pr₆O₁₁ and TeO₂ in a CsCl flux at 1123 K. This compound, which is isostructural with Nd₂Te₄O₁₁ and Ho₂Te₄O₁₁, crystallizes in space group C2/c of the monoclinic system with four formula units in a cell of dimensions at 153 K of a = 12.6880(6) Å, b = 5.2361(3) Å, c = 16.2920(8) Å, β = 106.052(1)°, and V = 1040.17(9) Å³. The three dimensional structure is made from the interconnection between _∞²[Pr₂O₁₀^14-] and _∞²[Te₄O₁₁^6-] networks. Pr₂Te₄O₁₁ is a Curie-Weiss paramagnetic with an effective magnetic moment of 3.59(2) μ_B. Optical diffuse reflectance spectroscopy shows typical 4f-4f optical transitions for Pr(III), in addition to a wide band gap of 3.65 eV.
