Bobjonesite, V4+ O (SO4) (H2O)3, a new mineral species from Temple Mountain, Emery County, Utah, U.S.A

Bobjonesite, V⁴⁺ O (SO₄) (H₂O)₃, is a new mineral species from Temple Mountain, Emery County, Utah, U.S.A. It occurs as blue-green crusts and efflorescences in fractures in a fossil (Triassic) tree; individual crystals are 5>F) reflections measured with an automated four-circle X-ray diffractometer using MoKα X-radiation. There is one V site occupied by V⁴⁺ and surrounded by three O atoms and three (H₂O) groups in an octahedral arrangement, with one short vanadyl bond (1.577 Å), four similar equatorial bonds (<2.022 Å>), and one longer V–O bond (2.278 Å) trans to the vanadyl bond. The structure consists of isolated [V⁴⁺₂ O₂ (H₂O)₆ (SO₄)₂] clusters linked by hydrogen bonds.
