The title molecule, [Cu(C12H8N2)2(H2O)](NO3)2, is a new polymorph of a compound which up to now has been reported to crystallize space groups inC2/candCc. The crystal studied was twinned by non-merohedry (final BASF factor of 0.40043) with the structure being solved and refined inP-1. The CuIIatom is coordinated by four N atoms from two 1,10-phenanthroline ligands and an O atom from a water molecule in an approximate trigonal–bipyramidal geometry. Discrete entities of one cation and two nitrate anions are formed by water–nitrate O—H...O hydrogen bonds. The components are further assembled into a three-dimensional network by C—H...O hydrogen bonds.

The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octahedral coordination environment defined by three chlorido ligands, an oxygen atom from a water molecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N—H...O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex [Sn(H2O)Cl3(C2O4)]−anion. Neighbouring stannate(IV) anions are linked through O—H...O hydrogen bonds involving the water molecule and the two non-coordinating oxalate oxygen atoms. In combination with additional N—H...Cl hydrogen bonds between cations and anions, a three-dimensional network is spanned.

The cation of the complex title salt, [Zn(C13H11N3)2(H2O)](NO3)2, lies about a twofold rotation axis, which passes through the ZnIIatom and the O atom of the aqua ligand. The ZnIIatom adopts a distorted trigonal–bipyramidal geometry defined by two N atoms in axial positions [angle = 166.24 (7)°], and two N and one O atom in the equatorial plane [range of angles: 115.17 (7)–122.42 (3)°]. The dihedral angle between the imidazole and aniline rings is 23.86 (5)°. In the crystal, N—H...O and O—H...O hydrogen bonds link the components into a three-dimensional network.

The asymmetric unit of the title salt, C8H14N22+·2NO3−, contains two independent dications and four independent nitrate anions. The crystal structure consists of discrete nitrate ions, three of which stack in layers parallel to (001) atz= 0 and 0.5. These layers are connectedvia m-xylylenediaminium dications. The fourth anion is sandwiched by the two independent organic cations in the asymmetric unit. In the crystal, the ions are connected by a large number of bifurcated and non-bifurcated N—H...O(O) hydrogen bonds, forming sheets parallel to (100). These sheets are connected by C—H...O hydrogen bonds, forming a three-dimensional network.

The complete 1,4-BDC ligand is generated by inversion symmetry; it bridges two ZnII atoms to form a dinuclear complex. Neighbouring complexes interact through π–π contacts and various kinds of hydrogen bonds, leading to a two-dimensional supramolecular structure.
