1. Bis(diisobutylammonium) tetrachloridobis[3-(trifluoromethyl)phenyl]stannate

   https://doi.org/10.1107/S2414314623009136  

   Song, Xueqing; Li, William (October 2023, IUCrData)

   The asymmetric unit in the title salt, (C₈H₂₀N)₂[SnCl₄(C₇H₄Cl₂F₃)₂], features a di-isobutylammonium cation in a general position and a diorganotin tetrachloride dianion,i.e. tetrachloridobis(3-trifuoromethylphenyl)stannate(IV), located on a centre of inversion; the Sn^IVatom is octahedrally coordinated. In the crystal, charge-assisted N⁺—H...Cl hydrogen bonds along with C—H...F contacts occur within supramolecular layers that interdigitate along thea-axis direction.

2. 4,4'-(Ethene-1,2-diyl)dipyridinium bis(2-hydroxy-3-methoxybenzoate)

   In the title double proton-transfer salt, C 12 H 12 N 2 2+ ·2C 8 H 7 O 4 − , consisting of a 1:2 ratio of 4,4'-(ethene-1,2-diyl)dipyridinium cations ( trans bipyridinium ethylene) to 2-hydroxy-3-methoxybenzoate anions ( o -vanillate), the complete cation is generated by crystallographic inversion symmetry and it is linked to adjacent o -vanillate anions by N—H...O hydrogen bonds, forming trimolecular assemblies. The trimers are linked by C—H...O hydrogen bonds as well as aromatic π–π stacking interactions into a three-dimensional network. The anion features an intramolecular O—H...O hydrogen bond.
