The asymmetric unit of the new title melaminium salt, C3H7N6+·C7H7O3S-·H2O, comprises a melaminium cation, a 4-methylbenzenesulfonate anion and a water molecule. Extensive intermolecular interactions, including hydrogen bonding, feature in the crystal structure.
metal-organic compounds
In the title compound, [Cu(C2H6N5)2]·2H2O, the Cu2+ cation, lying at a centre of symmetry, is coordinated by four N atoms from two bidenate ligands, forming a square-planar complex. The deprotonation of the ligand causes an increase in π-conjugation. Hydrogen bonds between solvent water and the complex help to stabilize the three-dimensional network structure.
metal-organic compounds
The title compound, [Cu2(OH)2(C12H8N2)2(H2O)2](C8H4O4)·8H2O, was prepared by the hydrothermal reaction of CuCl2, 1,10-phenanthroline, terephthalic acid and water at 443 K. It consists of a double-hydroxo-bridged dinuclear complex cation [CuCu = 2.911 (3) Å], a terephthalate anion and eight water molecules. Both cation and anion possess inversion symmetry. A network of O—HO hydrogen bonds stabilizes the structure.

In the title compound, [CoCl(C24H21N7)]2[CoCl4]·4CH3OH, the crystal packing is stabilized by O—HCl, N—HCl and N—HO hydrogen bonds, weak C—HCl interactions, and π–π stacking. The anion lies on a twofold rotation axis.
metal-organic compounds
In the title compound, [Ni(C2H6N5)2]·2H2O, the Ni cation (site symmetry ) is coordinated by four N atoms from two bidenate ligands in a square-planar arrangement. A network of O—HN, N—HN and N—HO hydrogen bonds helps to consolidate the crystal packing.
