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 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 (), 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.
