Butane-1,2,3,4-tetracarboxylic acid dihydrate
The asymmetric unit of the title compound, C(8)H(10)O(8)·2H(2)O, contains one half-mol-ecule of butane-1,2,3,4-tetra-carboxylic acid and a water mol-ecule, with the complete tetra-acid generated by crystallographic inversion symmetry. Inter-molecular O-H⋯O hydrogen bonds form an extensive three-dimensional network, which consolidates the crystal packing.

In the title compound, C(4)H(14)N(2) (+)·2C(9)H(7)O(4) (-)·2H(2)O, the butane-1,4-diaminium cation lies on an inversion center. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the components into layers parallel to (100). Addtional stabilization within these layers is provided by weak inter-molecular C-H⋯O hydrogen bonds.

The organic cation in the title compound, C(14)H(18)N(2) (2+)·2Br(-)·2H(2)O, is situated on an inversion centre. The cations, anions and water mol-ecules are linked via O-H⋯Br, C-H⋯Br and C-H⋯O hydrogen bonds, and π-π stacking inter-actions between adjacent pyridine rings, with a centroid-centroid separation of 3.8518 (17) Å.

In the title compound, (C(10)H(16)N(4))[ZnCl(4)]·2H(2)O, the cation lies abouton a center of inversion and the anion about a twofold rotation axis. The Zn(II) atom is four-coordinate in a tetra-hedral environment. The cations, anions and water mol-ecules are linked by N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds into a two-dimensional network.
متن کامل5,5′-(Butane-1,4-diyl)bis(1H-tetrazole) dihydrate
The title compound, C(6)H(10)N(8)·2H(2)O, was prepared by the reaction of hexanedinitrile and sodium azide. The di-1H-tetra-zole mol-ecule lies on a crystallographic centre of inversion and is linked to the water mol-ecules by N-H⋯O and O-H⋯N hydrogen bonds, forming a two-dimensional supra-molecular structure in the crystal.
