La₅Mo₆O₂₁: a novel ternary reduced molybdenum oxide containing {Mo^IV}₃ clusters and isolated Mo^V centres

The crystal structure of La₅Mo₆O₂₁ (penta­lanthanum hexa­molybdenum henicosa­oxide) is made up of Mo₃O₁₃ units containing triangular {Mo^IV}₃ clusters, three distorted Mo^VO₆ octa­hedral units and six inter­stitial La^III atoms. The Mo₃O₁₃ unit consists of three edge-sharing Mo^IVO₆ units involving Mo—Mo bonding. The three Mo^VO₆ octa­hedra share their corners or edges with each other and with the Mo₃O₁₃ units.

Sm₅Ga₃

In the single-crystal structure of Sm₅Ga₃, the tetra­gonal P4/ncc unit cell contains four isolated Ga atoms and four Ga₂ dumbbells, with Ga—Ga bond lengths of 2.653 (3) Å.

Potassium cerium(III) bis­(sulfate) monohydrate, KCe(SO₄)₂·H₂O

The crystal structure of KCe(SO₄)₂·H₂O consists of irregular independent SO₄ tetra­hedra, CeO₉ polyhedra in the form of distorted tricapped trigonal prisms and K⁺ ions.

Thallium(III) selenite, Tl₂(SeO₃)₃

Tl₂(SeO₃)₃ is built up from TlO₆ octa­hedra, TlO₇ distorted penta­gonal bipyramids and (SeO₃)²⁻ pyramids sharing vertices and edges to form corrugated (001) layers. The Se lone pairs of electrons are accommodated in the inter­layer regions.

Sodium calcium orthovanadate, NaCa₄(VO₄)₃

NaCa₄(VO₄)₃ is isostructural with the mineral silicocarnotite. The structure consists of isolated VO₄ tetra­hedra linked by disordered calcium and sodium cations disordered over eight- and seven-coordinated sites.
