Indexed X-ray powder diffraction data are reported for two organic salts with carbon rings having two quaternary nitrogens: diazonia-6,9 dispiro [5.2.5.2] hexadecane and diazonia-6,9 dispiro [5.2.5.3] heptadecane diiodides. For these compounds, which give solid electrolytes when associated with AgI, powder diffraction diagrams calculated by the Rietveld method from single crystal structure determinations are presented and are compared to the experimental diffraction data.

In this work, structural characterization of selected perovskite-type compounds from Ba[Formula: see text]Gd[Formula: see text]Zr[Formula: see text]SnxInyO[Formula: see text] group is given, including high temperature XRD measurements. An evidence of water incorporation into the crystal structure of the materials in a form of OH[Formula: see text] is discussed on a basis of thermogravimetric studies, with mass spectroscopy analysis of the gases released from samples on heating/cooling. As expected, oxygen non-stoichiometry was found to play a dominant role concerning possibility of water uptake. In addition, a rather strong affinity of the materials towards CO2 was documented, which seems to be a problem concerning possible application of the compounds as proton conducting solid electrolytes.

Linear Coordination

Bis(p-tolylsulfonylmethylisocyanide)silver nitrate is obtained from the reaction of the isocyanide ligand with silver nitrate in chloroform regardless of the applied ratio of the reactands (1:1 or 2:1). The crystal structure of the product has been determined. In the complex molecule with C2 symmetry, the nitrate anion is attached to the silver center as an η2-chelating ligand. Owing to this approach of the NO3 ligand, the RNC-Ag-CNR axis (R = 4-Me-C6H4-SO2-CH2) is bent [from 180 to 162.1(2)°], but the geometry of the nitrate is not significantly distorted, suggesting only weak coordinative bonding. The structure is thus intermediate between that of a molecular complex with a tetrahedral coordination and that of an ionic compound with linear coordination of the silver center.

Molecular crystals have attracted increasing attention as a candidate for innovative solid electrolytes with solid-state Mg-ion conductivity. In this work, we synthesized a novel Mg-ion-conducting molecular crystal, Mg{N(SO2CF3)2}2(CH3OC5H9)2 (Mg(TFSA)2(CPME)2), composed of Mg bis(trifluoromethanesulfonyl)amide (Mg(TFSA)2) and cyclopentyl methyl ether (CPME) and elucidated its crystal structure. We found that the obtained Mg(TFSA)2(CPME)2 exhibits solid-state ionic conductivity at room temperature and a high Mg-ion transference number of 0.74. Contrastingly, most Mg-conductive inorganic solid electrolytes require heating above 150–300°C to exhibit ionic conductivity. These results further prove the suitability of molecular crystals as candidates for Mg-ion-conducting solid electrolytes.

The structure of tetraphenylphosphonium tetrakis(trimethylsilanolato)ferrate(III), [(C6H5)4P][Fe(OSi(CH3)3)4], has tetragonal (I-4) symmetry, and was refined as an inversion twin. It is an ionic compound consisting of a tetraphenylphosphonium cation and a tetrakis(trimethylsilanolato)ferrate(III) anion. The crystal structure comprises the two ionic species each centered on a -4 symmetry element and contributing a fourth of its structure to the asymmetric unit. Each is surrounded by counter-ions on all sides. The cation contains a central phosphorous atom bound to four phenyl groups in a tetrahedral arrangement, while the anion contains a central iron(III) atom tetrahedrally coordinated by four trimethylsilanolato ligands.
