Cover illustration: The molecular structure of (BETS)2[Fe(tdas)2]2, showing the dimerization of each entity. Displacement ellipsoids are drawn at the 50% probability level and H atoms have been omitted for clarity. See Pilia, Faulmann, Malfant, Collière, Mercuri, Deplano & Cassoux [Acta Cryst.

Hg3Se3O10 was obtained after hydrothermal treatment of microcrystalline HgSeO4. The structure consists of three crystallographically independent Hg atoms, two selenite(IV) anions and one selenate(VI) anion.
Ba14Cu2In4N7 crystallizes in the monoclinic space group P2/m with Z = 2, and contains 0[CuN2] nitridocuprate units and distorted 0[In4] clusters. One Ba atom, not connected to any N atoms, is surrounded by 12 other Ba atoms in a barium cuboctahedron.
