The heterometallic coordination compound [Cu(Lys)(phen)]2V4O12·4H2O (Lys is the amino acid lysine, C6H14N2O2, and phen is 1,10-phenanthroline, C12H8N2) lies across an inversion centre. Two [Cu(Lys)(phen)]2+ units coordinate to the cyclo-vanadate fragment and the formula unit is completed by four solvent water molecules. The lysine ligand is in the zwitterionic form and chelates the CuII atom via the α-NH2 and α-COO− donor groups, while the ∊-NH3 + group is involved in intramolecular hydrogen bonds with the central [V4O12]4− core and with solvent water molecules. In the crystal, N—H...O and O—H...O hydrogen bonds connect the components of the structure to form a three-dimensional network. The crystal structure is further stabilized by π–π interactions involving the phen ligands. The lysine group is disordered over two sets of sites with refined occupancies of 0.534 (11) and 0.466 (11).

In the title polymeric complex, {[CoSr(C7H3NO4)2(H2O)6]·2H2O}n, the CoIIion, which is situated on a crystallographic centre of inversion, is six-coordinated by two O atoms and two N atoms from two pyridine-2,4-dicarboxylate (pydc2−) ligands and two terminal water molecules in a slightly distorted octahedral geometry, to form atrans-[Co(pydc)2(H2O)2]2−unit. The SrIIion, situated on aC2axis, is coordinated by four O atoms from four pydc2−ligands and four water molecules. The coordination geometry of the SrIIatom can be best described as a distorted dodecahedron. Each SrIIion bridges four [Co(pydc)2(H2O)2]2−units by four COO−groups of four pydc2−ligands to form a three-dimensional network structure. Two additional solvent water molecules are observed in the crystal structure and are connected to the three-dimensional coordination polymer by O—H...O hydrogen bonds. Further intra- and intermolecular O—H...O hydrogen bonds consolidate the overall structure.

In the structure of the brucinium salt of 4-aminophenylarsonic acid (p-arsanilic acid), systematically 2,3-dimethoxy-10-oxostrychnidinium 4-aminophenylarsonate tetrahydrate, (C23H27N2O4)[As(C6H7N)O2(OH)]·4H2O, the brucinium cations form the characteristic undulating and overlapping head-to-tail layered brucine substructures packed along [010]. The arsanilate anions and the water molecules of solvation are accommodated between the layers and are linked to them through a primary cation N—H...O(anion) hydrogen bond, as well as through water O—H...O hydrogen bonds to brucinium and arsanilate ions as well as bridging water O-atom acceptors, giving an overall three-dimensional network structure.

The asymmetric unit of the title compound, 2,4,6-triamino-1,3,5-triazin-1-ium cyanoacetate monohydrate, C3H7N6 +·NCCH2COO−·H2O, consists of a melaminium cation, a cyanoacetate anion and a water molecule, which are connected to each other via N—H...O and O—H...O hydrogen bonds, generating an eight-membered ring. In the crystal, the melaminium cations are connected by two pairs of N—H...N hydrogen bonds, forming tapes along [110]. These tapes develop a three-dimensional network through N—H...O, O—H...O, N—H...N and C—H...O hydrogen bonds between the cations, anions and water molecules.

The cation, but not the neutral taci unit, exhibits intramolecular O—H...O hydrogen bonding. The entire structure is stabilized by a complex three-dimensional network of intermolecular hydrogen bonds. The neutral taci entities and the Htaci+cations are each aligned into chains along [001]. In these chains, two O—H...N interactions generate a ten-membered ring as the predominant structural motif. The rings consist of vicinal 2-amino-1-hydroxyethylene units of neighbouring molecules, which are pairedviacentres of inversion. The chains are interconnected into undulating layers parallel to theacplane, and the layers are further held together by O—H...N hydrogen bonds and additional interactions with the iodide counter-anions and solvent water molecules.

The central structural motif of the title coordination polymer, [Co(NO3)2(C4H4N2)(CH3CN)2(H2O)2]n, is a chain composed of CoIIions linked by bis-monodentate bridging pyrazine ligands through their N atoms. The CoIIion is located on an inversion center and is additionally coordinated by two O atoms of water molecules and two N atoms of acetonitrile molecules. The resultant N4O2coordination sphere is distorted octahedral. The linear cationic chains extend parallel to theaaxis and are aligned into layers parallel to theacplane. Nitrate anions are situated in the space between the CoIIchains and form O—H...O hydrogen bonds with the coordinating water molecules, leading to a three-dimensional network structure. Weak C—H...O hydrogen bonds are also present between pyrazine or acetonitrile molecules and the nitrate anions.
