In the title compound, the complete organic cation, which adopts a typical chair conformation, is generated by crystallographic inversion symmetry and one of the N-bonded H atoms is half occupied. The sodium ion (site symmetry m) at the centre of the complex anion adopts a distorted trigonal–bipyramidal coordination geometry with the water molecules in the equatorial sites and the bromide ions in the axial sites. In the extended structure, O—H⋯Br hydrogen bonds generate a porous ‘honeycomb’ three-dimensional network of complex anions encapsulating [010] channels occupied by the cations.

A new electron-rich, bidentate phosphine, 1,2-bis[di(benzofuran-2-yl)phosphanyl]ethane, was synthesized and structurally characterized by single-crystal X-ray diffraction.
The title compound, C34H24O4P2, consists of an ethylene-bridged diphosphine with benzofuran residues, where the P—C—C—P backbone exhibits an anti-conformation. The asymmetric unit contains one half molecule, which is completed by inversion symmetry.

The extended structure of the title compound features strong N—H⋯N hydrogen bonds forming infinite C(4) chains propagating along the c-axis direction.
The title compound, C16H18N2, is a non-symmetrically N,N′-disubstituted acetamidine having a phenyl and a bulky 2,6-dimethylphenyl as substituents on the two N atoms of the N—C—N linkage. It crystallizes in an E-syn configuration and its amidine C—N bonds present distinct amine [1.366 (1) Å] and imine [1.288 (1) Å] bond lengths. In the extended structure, strong N—H⋯N hydrogen bonds link the molecules into infinite C(4) chains propagating along the c-axis direction; weak C—H⋯π interactions are also present in the crystal packing.
