The asymmetric unit of the title complex, [Co(NO3)(C10H8N2)(H2O)3]Cl, consists of a chloride anion and a complex cation, which is built on a monodentate nitrate anion, three water molecules and one bidentate 2,2′-bipyridine molecule, coordinated to a CoII cation, in a distorted octahedral geometry. The water molecules are arranged in a facial geometry, and serve as donors for hydrogen bonding. Acceptor sites in the crystal are chloride ions and one O atom of the coordinating nitrate ion. A three-dimensional framework is formed, based on O—H...O and O—H...Cl contacts.

The asymmetric unit of the title compound, [Mn(C7H4BrO2)(C12H8N2)2(H2O)](C7H4BrO2)·2H2O, consists of a monovalent [Mn(C7H4BrO2)(C12H8N2)2(H2O)]+complex cation, a 4-bromobenzoate anion and two lattice water molecules. In the complex cation, the MnIIatom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands and two O atoms, one from a 4-bromobenzoate anion and the other from a coordinating water molecule. This completes an MnN4O2coordination sphere with a distorted octahedral geometry. The Br atom of the bromobenzoato ligand is equally disordered over two sites. In the crystal, the complex cations are connected to each otherviaO—H...O, O—H...Br and C—H...O hydrogen bonds and π–π stacking interactions [closest separation = 3.492 (4) Å]. π–π contacts [closest separation = 3.771 (4) Å] also link the complex cations to both the coordinated and non-coordinating 4-bromobenzoate anions. Overall, these contacts generate a three-dimensional network structure.

The asymmetric unit of the title compound, (C13H11N2)[Fe(C7H3NO4)2]·4H2O, contains a 9-aminoacridinium cation, one anionic complex and four uncoordinated water molecules. In the anionic complex, the FeIII ion is six-coordinated by two almost perpendicular [dihedral angle = 88.78 (7)°] pyridine-2,6-dicarboxylate ligands in a distorted octahedral geometry. In the crystal, anions are connected into chains along [10-1] by weak C—H...O interactions, which create ten-membered hydrogen-bonded R 2 2(10) rings. These chains are linked by three-membered water clusters. The final three-dimensional network is constructed by numerous intermolecular O—H...O and N—H...O interactions.

The asymmetric unit of the title compound, {[Mn3{W(CN)8}2(C16H16N2)3(C3H7NO)3(CH3OH)3]·2H2O}n, consists of three [Mn(N,N-dimethylformamide)(methanol)(3,4,7,8-tetramethyl-1,10-phenanthroline)]2+cations, two [W(CN)8]3−anions and two water molecules. Each water molecule is disordered over three sets of sites, with a refined occupancy ratio of 0.310 (9):0.275 (9):0.415 (9) for one molecule and 0.335 (9):0.288 (9):0.377 (9) for the other molecule. The MnIIatoms exhibit a distorted octahedral geometry, while the WVatoms adopt a distorted square-antiprismatic geometry. The MnIIand WVatoms are linked alternatively through cyanide groups, forming a tetranuclear 12-atom rhombic metallacycle. Adjacent metallacycles are further connected by μ2-bridging cyanide anions, generating a 3,2-chain structure running parallel to [101]. Interchain π–π interactions are observed [centroid–centroid distances = 3.763 (3) and 3.620 (2) Å].

The 5-carboxybenzene-1,2,4-tricarboxylate ligands bridge the CdII ions, resulting in the formation of a three-dimensional structure. Intra- and intermolecular O—H...O hydrogen bonds are present throughout the three-dimensional structure.
