In the title complex, [Ni(C12H9N2O3S)2(H2O)2]·4H2O, the NiII ion is coordinated by four N atoms from two bidentate chelating 4-[(pyridin-2-yl)methylideneamino]benzenesulfonate ligands and two O atoms from cis-related water molecules in a slightly distorted octahedral environment [Ni—N = 2.071 (3)–2.121 (3) Å and Ni—O = 2.071 (2) and 2.073 (3) Å]. In the crystal, the coordinated water molecules and the four water molecules of solvation are involved in intermolecular O—H...O hydrogen-bonding interactions with water and sulfonate O-atom acceptors, giving a three-dimensional framework structure.

The title compound, [Co(C6H6NO3S)2(H2O)2] n , was obtained from a mixture of Co(NO3)2·6H2O and a previously synthesized salt, namely CyNH3·NH2PhSO3, in a 1:1 ratio (Cy = cyclohexyl; Ph = phenyl). The crystal structure consists of a three-dimensional supramolecular framework, in which polymeric layers are interconnected via N—H...O and O—H...O hydrogen bonding. The polymeric layers are formed by an interconnection of neighbouring cobalt(II) cations via NH2PhSO3 − bridges. Each cobalt(II) cation is surrounded by four NH2PhSO3 − moieties and two water molecules, leading to a distorted octahedral environment.

The polymeric title compound, {[Co(C15H9NO4S)(H2O)3]·H2O}n, consists of chains along [001] made up from Co2+ions bridged by 10-methylphenothiazine-3,7-dicarboxylate anions. The Co2+ion, coordinated by three O atoms from two different carboxylate groups and three water molecules, displays a distorted octahedral environment. In the crystal, π–π interchain interactions, with centroid–centroid distances of 3.656 (2) and 3.669 (2) Å between the benzene rings of the ligands, assemble the chains into sheets parallel to (100). O—H...O hydrogen-bonding interactions between the coordinating water molecules and carboxylate O atoms link the sheets into a three-dimensional network.

The asymmetric unit of the title complex, [Co(C5H5N3O)2(H2O)2](NO3)2, contains one half of a CoIIcationic unit and a nitrate anion. The entire [Co(C5H5N3O)2(H2O)2]2+cationic unit is completed by the application of inversion symmetry at the CoIIsite, generating a six-coordinate distorted octahedral environment for the metal ion. The chelating pyrazine-2-carboxamide molecules are bound to cobaltviaN and O atoms, forming a square plane, while the remaining twotranspositions in the octahedron are occupied by two coordinated water molecules.

The title complex, [Ni(C10H8N3O2)2]·CH3OH, is a mononuclear nickel(II) compound containing two di-2-pyridylamine N,N′-dioxide (dpa dioxide) ligands that are nearly perpendicular to each other. The NiII ion of the complex has a distorted octahedral environment with the equatorial plane formed by an N atom from each amine group and two O atoms of one ligand, while the axial positions are occupied by two O atoms of the second ligand. In the solid state, hydrogen-bonding interactions are dominant, with solvent molecules also participating in hydrogen bonding.

In the title complex, [Mn(N3)2(C8H8N6)2], the complete molecule is generated by the application of twofold symmetry, and is in a distorted octahedral environment, coordinated by four N atoms of two bidentate 6-(pyridin-2-yl)-1,3,5-triazine-2,4-diamine ligands and two N atoms from two azide anions. The two chelated 6-(pyridin-2-yl)-1,3,5-triazine-2,4-diamine ligands form a dihedral angle 74.75 (5)°. The mononuclear molecules are alternatively linked into layers parallel to theacplaneviaN—H...N hydrogen bonds. Adjacent layers are connected into a three-dimensional supramolecular framework by futher N—H...N hydrogen-bonding interactions.

Intermolecular O—H...O hydrogen-bonding interactions among the coordinated water molecules, solvent water molecules and carboxyl O atoms of the organic ligand and additional N—H...O hydrogen bonding lead to the formation of a three-dimensional supramolecular network.

Distorted Octahedral

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

The mononuclear title complex, [Fe(CF3O3S)(C5H7O2)2(C4H8O)] or [Fe(acac)2(OTf)(THF)] (acac = acetylacetonate; OTf = trifluoromethanesulfonate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe3+atom in a slightly distorted octahedral environment [Fe—O bond-length range = 1.9517 (11)–2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622 (16):0.378 (16). Weak intermolecular C—H...O and C—H...F hydrogen-bonding interactions generate a two-dimensional supramolecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis(acetylacetonato)iron(III) complex.

In the title complex, [CoIIICl(C2H8N2)2(C2H3N3)]Cl2, the CoIIIion has a distorted octahedral environment. It is surrounded by four N atoms in the equatorial plane, with another N atom and a Cl atom occupying the axial positions. Both five-membered Co—N—C—C—N rings adopt a twist conformation. The Co—N bond lengths range from 1.941 (2) to 1.954 (1) Å, while the Co—Cl bond length is 2.257 (1) Å. In the crystal, molecules are linked by N—H...N, N—H...Cl and C—H...Cl hydrogen bonds. Dimers are formed by N—H...Cl hydrogen-bonding interactions between amine H-atom donors and chloride ions resulting in anR42(8) ring motif. These dimers are further connected in a head-to-tail fashionviaN—H...Cl and C—H...Cl hydrogen bonds. All the interactions together combine to link the molecules into a three-dimensional framework.
