Cover illustration: The structure of one of the two independent mol­ecules of 3,3,6,6,9,9-hexaethyl-1,2,4,5,7,8-hexa­oxacyclo­nonane (DEKTP). Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. See Cerna, Bernès, Cañizo & Eyler [Acta Cryst. (2009), C65, o562-o564].

The crystal structure of the Sb-rich variety of the mineral gustavite, AgPb(Bi2Sb)3S6, a naturally occuring monoclinic lillianite homologue with N = 4, has been solved and refined for the first time by means of single-crystal X-ray diffraction. The crystal structure consists of blocks of diagonal chains of four octa­hedra, viz. M1a (Bi), M2a (Sb/Bi), M2b (Bi/Sb) and M1b (Ag), separated by Pb atoms in a trigonal prismatic coordination.

The crystal structure of sodium magnesium sulfate deca­hydrate was solved and refined for the first time. Alternating layers of [Mg(H2O)6]2+ and [Na2(SO4)2(H2O)4]2− ions, parallel to [100], are held together by hydrogen bonding.

A new polymorph of nona­copper(II) bis­(orthoborate) bis­(hexa­oxodiborate), Cu9(BO3)2(B2O6)2, or Cu3B2O6 with Z′ = 3, has a pseudo-layered monoclinic structure containing BO3 triangles and B2O6 units consisting of corner-sharing BO3 triangles and BO4 tetra­hedra. The compound was obtained during an investigation of the Li–Cu–B–O system. In contrast to the triclinic form of Cu3B2O6, the layers are linked to one another by BO4 tetra­hedra.
