Abstract

The new compounds M²⁺Zr(SeO₄)₃ (M²⁺ = Mg, Mn, Co, Ni, Zn, Cd) and Li₂Zr(
XO₄)₃ (X = S, Se) were synthesized at 220 °C by reaction of Zr₂O₂(CO₃)(OH)₂ with hydroxides or carbonates of M / Li and the respective acids H₂SeO₄/H₂SO₄. They form crystals up to several tenths of a mm and were investigated by single crystal X-ray diffraction. The framework structures of these selenates can be deduced from that of monoclinic Fe₂(SO₄)₃ in space group P2₁/n, which is characterized by two types of isolated Fe³⁺O₆ octahedra, corner-linked with three different sulfate groups: ferric iron is substituted in 1:1 ratio by Zr⁴⁺and M²⁺ as already known for isotypic MZr(SO₄)₃ representatives. In the case of Li₂Zr(XO₄)₃ members, one additional lithium atom occupies a tetrahedral vacancy of the Fe₂(SO₄)₃ architecture.
