By using (NH4)2TeO4 instead of TeO2, a fine powder consisting of microcrystalline spheres of K12+6xFe6Te4−xO27 was obtained. K12+6xFe6Te4−xO27 crystallizes in the acentric cubic space group Iurn:x-wiley:09476539:media:chem202102464:chem202102464-math-0001 3d. [FeIIIO5] pyramids share their apical atoms in [Fe2O9] groups and two of their edges with [TeVIO6] octahedra to form an open framework that consists of two loosely connected, but not interpenetrating, chiral networks. The flexibility of the hinged oxometalate network manifests in a piezoelectric response similar to that of LiNbO3.The potassium cations are mobile in channels that run along the <111> directions and cross in cavities acting as nodes. The ion conductivity of cold-pressed pellets of ball-milled K12+6xFe6Te4−xO27 is 2.3×10^(−4) S ⋅ cm^(−1) at room temperature. Magnetization measurements and neutron diffraction indicate antiferromagnetic coupling in the [Fe2O9] groups."}],"publication":"Chemistry – A European Journal","issue":"57","keyword":["General Chemistry","Catalysis","Organic Chemistry"],"type":"journal_article","date_created":"2023-10-11T08:39:51Z","status":"public","volume":27,"user_id":"22501","publisher":"Wiley","_id":"47977","page":"14299-14306","quality_controlled":"1","citation":{"chicago":"Albrecht, Ralf, Markus Hoelzel, Henrik Beccard, Michael Rüsing, Lukas Eng, Thomas Doert, and Michael Ruck. “Potassium Ion Conductivity in the Cubic Labyrinth of a Piezoelectric, Antiferromagnetic Oxoferrate(III) Tellurate(VI).” <i>Chemistry – A European Journal</i> 27, no. 57 (2021): 14299–306. <a href=\"https://doi.org/10.1002/chem.202102464\">https://doi.org/10.1002/chem.202102464</a>.","ama":"Albrecht R, Hoelzel M, Beccard H, et al.
