Single Crystal Growth and Crystal Structure of HgTeO2FOH — A Layered
Fluorohydroxooxotellurate(IV) Stabilized by Weak F···OH Interactions. —
Light-yellow crystals of the title compound are prepared hydrothermally from a solution of stoichiometric amounts of TeO2 and HgO in aq. HF (autoclave, 220 °C, 5 d).
HgTeO2FOH crystallizes in the space group Pca21 with Z = 4 (single crystal XRD). The
structure contains distorted [HgIIO4F2OH] polyhedra and (TeIVO2FOH) 2- anions as the
main building units which form a layered assembly. Adjacent layers are connected only
via F···OH interactions. — (WEIL, M.; J. Alloys Compd. 386 (2005) 1-2, 119-124;
