metal-organic compounds
The coordination environment of copper(II) in the title compound, [Cu(C6H4NO3)(NO3)(C12H8N2)], is square pyramidal; the basal plane comprises the two N atoms of 1,10-phenanthroline and the two O atoms of picolinate N-oxide, with the apical position occupied by a nitrate O atom.

A new one-dimensional coordination polymer, catena-poly[[aqua(nitrato-κ2O,O′)copper(II)]-μ-pyrazine-2-carboxylato- κ3N1,O:N4], [Cu(C5H3N2O2)(NO3)(H2O)]n, has been synthesized and characterized. The coordination environment of the copper(II) ion is distorted octahedral, arising from an N,O-bidentate 2-pyrazinecarboxylate ligand, an N atom from a symmetry-related 2-pyrazinecarboxylate ligand, a bidentate nitrate group and a water molecule. The chains interact by way of O—H

The title compound, [Co(C12H8N2)(H2O)4]2(C10H2O8), consists of discrete tetraaqua(1,10-phenanthroline)cobalt(II) cations and 1,2,4,5-benzenetetracarboxylate anions. The CoII atom is octahedrally coordinated by two N atoms of the 1,10-phenanthroline ligand and four O atoms of water molecules. The anion lies on an inversion centre. A two-dimensional hydrogen-bonding network is formed by O atoms of benzenetetracarboxylate and the coordinated water molecules.
organic compounds
The title compound, C9H11N4O2S, consisting of a pyrimidine ring and a thiourea carboxylic acid methyl ester, possesses mirror symmetry and an intramolecular N—HN hydrogen bond. In the crystal structure, N—HS hydrogen bonds link symmetry-related molecules to form dimers, which in turn are linked by a C—HO hydogen bond to form a two-dimensional planar structure.
