The structure of [CoCl(NH3)5][Ru(NO2)4(OH)(NO)] consists of octahedral [CoCl(NH3)5]2+ and [Ru(NO2)4(OH)(NO)]2− ions held together via a three-dimensional network of inter- molecular O—H⋯O, N-H⋯O and N-H⋯Cl hydrogen bonds.
The structure of [Co(NH3)6](S2O3)Cl.H2O consists of discrete ions and water molecules of hydration linked by weak hydrogen bonds and interionic contacts.
Cs2Au2I6 has a distorted perovskite structure, isomorphous with the Wells salt Cs2Au2Cl6. The interatomic distances in Cs2Au2I6 show that the mixed-valence state of the iodide is not the same as that of the chloride.
SmMo8O14 is isostructural with NdMo8O14. The structure contains cis-edge-sharing bi-face-capped octahedral Mo8 clusters arranged in layers. The O-atom framework is derived from the close-packing layer sequence ABAC. The Sm3+ ions are surrounded by 12 O atoms forming a distorted cuboctahedron.
