Abstract

We report synthesis and crystal structure of a new copper molybdate oxosulfate Cu₆O₂(MoO₄)₃(SO₄). The new compound is obtained in evacuated silica ampoules at 675-725 °C. Cu₆O₂(MoO₄)₃(SO₄) is monoclinic, space group P2₁/m, a = 7.5208(4) Å, b = 6.8602(3) Å, c = 14.0019(7) Å, β = 93.471(5)°, V = 721.09(6) Å³, R₁ = 0.051. The 3D framework of the new compound consists of oxo-centered [OCu₃]⁴⁺ chains and MoO₄ and SO₄ tetrahedra. The structural motif of the new compound is related to the previously described fumarole minerals, glikinite Zn₃O(SO₄)₂ and vergasovaite Cu₃O(MoO₄)(SO₄). The crystal chemical peculiarities of this group of synthetic compounds and minerals are discussed.
