The structure of tetralithium octafluoridozirconate has been redetermined by high-resolution single-crystal X-ray diffraction. This result is largely consistent with a prior report, but with significant improvements in precision.

An unexpected product was obtained from slow evaporation in acidic media, as a protonated nitrogen is combined with a disulfide bond between a pair of 2-mercaptonicotinic acid moieties.

Eu6Sb6S17 is isotypic with Sr6Sb6S17 and can be regarded as consisting of two isolated [Sb3S7]5- anions and an S32- polysulfide anion that are joined together by Eu2+ cations. There are six crystallographically unique Eu2+ cations bound by sulfide and polysulfide anions in seven-, eight- and nine-coordinate environments. Each of the [Sb3S7]5- anions consists of a trinuclear assembly of corner-sharing SbS3 units. The [Sb3S7]5- anions are connected by long (3.1 Å) Sb-S interactions, forming one-dimensional ribbons running down the a axis and packed with opposing directions of polarity. The bent S32- anions stack in columns parallel to the a axis, oriented in opposing directions with respect to one another. The overall structure is three-dimensional and has channels running down the a axis to house the stereochemically active lone pair of electrons on the Sb3+ centers. The presence of Eu2+ is supported by both magnetic measurements and bond-valence calculations.

In the anion of the title compound, (C6H11N2)[B5O6(OH)4], both six-membered borate rings adopt a flattened boat conformation with the spiro-B atom and its opposite O atom deviating from the remainders of the rings by 0.261 (3)/0.101 (2) and 0.160 (3)/0.109 (2) Å, respectively. The imidazolium cation also deviates from planarity due to rotation of the ethyl group (as indicated by the C—N—C—C torsion angle) by 71.4 (2)° out of the plane of the heterocycle. In the crystal, the anions are connected in a three-dimensional network through O—H
O hydrogen bonds, forming channels along the a-axis direction. The cations are situated in the channels, forming C—H
O hydrogen bonds with the anions.

The dinuclear AgI phosphine complex [Ag2(dppp)2]2+ [dppp = 1,3-bis(diphenylphosphino)propane] has been crystallized as the BF4− salt, viz. [Ag2(C27H26P2)2](BF4)2, in order to reduce the effects of coordination by the anion. The dimeric complex consists of two-coordinate AgI centers bridged by dppp ligands. The P—Ag—P bond angle deviates significantly from linearity, with a value of 159.66 (3)°. The Ag—P bond distances are close to being equal, with values of 2.3935 (7) and 2.4016 (7) Å. The cation has a center of symmetry midway between the two Ag atoms.

An organically templated neptunium(IV) fluoride compound, {(C2H10N2)[Np2F10]}n, has been synthesized under mild hydrothermal conditions. The compound crystallizes in the monoclinic space group C2/c (No. 15). The structure consists of NpF9 tricapped trigonal prisms connected through edge- and corner-sharing to form infinite two-dimensional [Np2F10]2- sheets, that are separated by the ethylenediammonium dications. The C2H10N22+ cations form hydrogen-bonding interactions with the [Np2F10]2- layers.

A new hydrated thorium chromate, Th(CrO4)2(H2O), has been synthesized under mild hydrothermal conditions. The structure consists of ThO8 dodecahedra and ThO9 tricapped trigonal prisms that are interconnected by chromate anions into a three-dimensional framework.

A caesium thorium(IV) silicate has been synthesized serendipitously under high-temperature solid-state conditions by the reaction of ThIV with a fused silica/alumina reaction crucible. The compound crystallizes in the orthorhombic space group Pca21. The crystal structure consists of ThO6 distorted octahedra corner-shared with SiO4 tetrahedra to form an anionic three-dimensional framework possessing extended channels containing Cs+ cations. Cs2ThSi6O15 is a phyllosilicate with the same sheet structure as β-K3NdSi6O15.
