Abstract: A single crystal of KVTeO5, potassium vanadium tellurite, has been grown. The present structure determination has been conducted together with the refinement of the NaVTeO5 homologue, sodium vanadium tellurite, for the sake of precise comparison. The network consists of [VTeO5]n ribbons built up by VO4 tetrahedra linking centrosymmetric Te2O6 groups and stacked along the [010] direction; the alkali cations are intercalated in between. The TeIV atom exhibits a typical one-sided coordination number (CN) of 4, completed by a lone pair, which forms a distorted triangular bipyramid with the four O atoms.
Formula: KVTeO5 and NaVTeO5
