Cover illustration: Superionic conductors are an important class of materials that find a wide range of applications in batteries and sensors. Silver ion superionic conductors are of particular interest. These are based on α-AgI, which is synthesized from β-AgI (with a wurzite-type of structure). In this article, Suzuki and collaborators present the structure of a novel silver iodide carbonate, Ag10(CO3)3I4, which is a precursor of one of the only two iodide/carbonate-containing compounds reported so far in the ICSD, Ag17(CO3)3I11. The Ag10(CO3)3I4 compound reported in this contribution displays an ionic conductivity comparable to that of AgI-based arsenate and phosphate compounds.

The structure of K[HgI3]·H2O was redetermined at 0.70 Å resolution, and its conventional refinement is compared to a refinement using non-spherical atomic form factors.

The title compound consists of cholesteryl and hepta­noate units, in which the six-membered rings adopt chair and twisted-boat conformations, while the five-membered ring adopts an envelope conformation. In the crystal, the mol­ecules are aligned along the a-axis direction and stacked along the b-axis direction.

A novel triiodide phase of the formamidinium cation, CH5N2+·I3, crystallizes in the triclinic space group P[\overline{1}] at a temperature of 100 K. The structure consists of two independent isolated triiodide ions located on inversion centers. The centrosymmetric character of I3 was additionally confirmed by the observed pronounced peaks of symmetrical oscillations of I3 at 115–116 cm−1 in Raman scattering spectra.

This new organic–inorganic hybrid compound contains stacked sheets of ethyl­endi­ammonium cations and [SnCl6]2− anions with p-anisaldehyde mol­ecules occupying occupying the space in between.

The title compound crystallizes with half of a mol­ecule per asymmetric unit and exhibits bond lengths and angles typical of α-diketones. A network of C—H⋯F contacts and π–π stacking inter­actions is observed within the structure.

The structure of the product obtained from the reaction of [Zr6O4(OH)4(ib)12(H2O)]·3Hib (Hib = isobutyric acid) with Sr(NO3)2 and H2mda (H2mda=N-methyldi­ethano­lamine) in the presence of MnCl2 and Et3N in aceto­nitrile was shown to be the one-dimensional coordination polymer [Sr(ib)2(H2mda)]n. Although manganese did not incorporate into the structure, its addition was the key to the isolation of a high-quality crystalline product.

In the title Schiff base hexa­nuclear copper(II) complex, two discrete environments are present in the structure: CuNO4 and CuNO3. Four copper(II) cations are situated in a distorted square-pyramidal environment, while two copper(II) cations are located in a slightly square-planar geometry. Three of the copper(II) cations occupy three vertices of an open cubane Cu3O4.

The structure of the title coordination polymer is determined by multiple hydrogen-bonding inter­actions. In the crystal, two ligands coordinate with the metal centre, generating chains, which are further connected with each other via N—H⋯O hydrogen bonds, and expanded into the final framework through additional N—H⋯O hydrogen bonds.

The di­thio­actal bis­[(benzyl­thio)­meth­yl]anthracene has been synthesized and reacted with [PdCl2(PhCN)2] to yield the cyclic cluster [Pd62-SCH2Ph)12].

The structure of bis­(2-methyl­pyridinium) tetra­chloro­cuprate(II) is characterized by layers formed by [C6H8N]+ and [CuCl4]2– connected through N—H⋯Cl and C—H(phen­yl)⋯Cl inter­actions. The layers are further connected by C—H(meth­yl)⋯Cl inter­actions.

The styryl and ester substituents are displaced to opposite sides of the plane through the pyridine ring while the acetyl group is rotated well out of that plane. In the crystal, inversion-related C—H⋯O hydrogen bonds form chains extending parallel to the a-axis direction, which pack with partial inter­calation of the styryl and ester substituents.

The new silver carbonate iodide, Ag10(CO3)3I4, comprises layers of I atoms, Ag atoms, and CO3 groups stacked along [10[\overline{1}]].

The mol­ecules are connected in the crystal by N—H⋯O hydrogen-bond pairs along the b-axis direction as dimers with [R_{2}^{2}](8) and [R_{2}^{2}](14) ring motifs and as ribbons by inter­molecular C—H⋯N hydrogen bonds. Between the ribbons, there are weak van der Waals contacts.

In this work, we present the complex salt [RuCp(PTA)2–μ-CN–1κC:2κ2N-RuCp(PTA)2][Re(NO)Br4(EtOH)0.5(MeOH)0.5]. The synthesis, single-crystal X-ray crystal structure, and magnetic properties are discussed.

In the title compound, the benzimidazole ring system is inclined to the the benzene ring by 78.04 (10)°. The crystal structure features O—H⋯N and C—H⋯O hydrogen bonding and C—H⋯π and π–π inter­actions.

In the crystal, mol­ecules are linked by pairs of N—H⋯O hydrogen bonds into ribbons along the c-axis direction. The layered crystal packing is further consolidated by van der Waals and C—H⋯π inter­actions.

Research communications

Research communications are designed to help authors bring out the science behind their structure determinations. Authors are encouraged to report more than one structure in the same communication and also to include the results of investigations with other techniques. The Research communications format makes Acta E the natural home for structure determinations with interesting science to report.
