Dilead mercury chromate(VI), Pb₂HgCrO₆

The structure of Pb₂HgCrO₆ consists of isolated [CrO₄]²⁻ tetrahedra, [HgO₂]²⁻ dumb-bells and stereochemically active Pb²⁺ ions with coordination 3+5.

Bismuth octaborate, Bi₂B₈O₁₅

In Bi₂B₈O₁₅, the Bi atom is coordinated to five or six O atoms. The B atoms exhibit two kinds of hybridization, sp² and sp³, seen in the BO₃ triangles and BO₄ tetrahedra, respectively. Three BO₃ triangles are connected to form a B₃O₆ planar ring. All atoms in the structure are connected together to form an infinite three-dimensional network.

New girdle-like Mo₁₈ polyanions linked into chains

The structure of the polyoxomolybdate [Na(H₂O)₁₆(NH₂CH₂COO)]⁴⁺·{Na⁺[H₉MoMoO₅₆(NH₂CH₂COO)]⁵⁻}⁴⁻·20H₂O is reported. The 18 Mo atoms connected by O atoms form a centrosymmetric girdle-like structure, in which Mo^V–Mo^V units are found. An Na⁺ cation occupies the central hole of the girdle, while four Na⁺ cations are bonded to O atoms on the girdle edge. The girdles are linked into a one-dimensional chain by the remaining Na⁺ cations.
