In the crystal structure of the title complex, [Mn(C2N3)2(C7H6N2)2] n or [Mn(dca)2(bim)2] n , where dca is dicyanamide and bim is benzimidazole, each MnII atom is located on a center of symmetry and is in a six-coordinated distorted octahedral environment. Four N atoms from four dca ligands fill the equatorial positions, and two N atoms from two bim ligands occupy the axial positions. The dicyanamide ligands adopt an end-to-end coordination mode and link the Mn atoms to form a two-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.

The title complex, [Mg(C7H7N4O2)2(H2O)4], lies across an inversion centre and the MgIIatom is coordinated in a slightly distorted octahedral environment by four aqua ligands in the equatorial sites and two 1,3-dimethyl-2,6-dioxo-3,7-dihydro-1H-purin-9-ide ligands, through imidazole ring N atoms, in the axial sites. An intramolecular O—H...O hydrogen bond forms anS(7) graph-set motif. In the crystal, O—H...O and O—H...N hydrogen bonds link complex molecules forming a three-dimensional network incorporatingR42(8) andR22(18) graph-set motifs.

The mononuclear copper title complex {N,N,N′,N′-tetrakis[(6-methylpyridin-2-yl)methyl]ethane-1,2-diamine-κ6N}copper(II) bis(tetrafluoridoborate), [Cu(C30H36N6)](BF4)2, is conveniently prepared from the reaction of Cu(BF4)2·6H2O withN,N,N′,N′-tetrakis[(6-methylpyridin-2-yl)methyl]ethane-1,2-diamine (tmpen) in acetonitrile at room temperature in air. The complex shows a distorted octahedral environment around the CuIIcation (site symmetry 2) and adopts the centrosymmetric space groupC2/c. The presence of the 6-methyl substituent hinders the approach of the pyridine group to the CuIIcore. The bond lengths about the CuIIatom are significantly longer than those of analogues without the 6-methyl substituents.

In the title compound, [Cd(C8H7O3)2(C14H12N2)], the CdIIion is coordinated by two N atoms from a 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and four O atoms from two 2-methoxybenzoate anions in a distorted octahedral environment. Two O atoms of one bidentate 2-methoxybenzoate ligand are each disordered over two positions, with site-occupancy factors of 0.579 (4) and 0.421 (4). In the crystal, molecules are linked by C—H...O hydrogen bonds, forming a two-dimensional network lieing parallel to thebcplane. The crystal packing is further stablized by π–π stacking interactions between the dmphen rings of neighboring molecules, with distances between their parallel dmphen ring planes of 3.517 (3) and 3.610 (3) Å.

The crystal structure contains 4,4′-bpy-bridged linear polymeric [Zn(4,4′-bpy)(H2O)3(ClO4)]n chains, where the zinc atom is coordinated in a distorted octahedral environment by two nitrogen atoms of the bridging 4,4′-bpy ligands (Z–N 2·104(2)–2·117(2) Å), three water molecules (Zn–O 2·068(2)–2·091(2) Å) and one monodentate ClO4- anion (Zn–O 2·320(2) Å).

Two tricarbonyl complexes of rhenium(I) and manganese(I) coordinated by the ligand 2-{[2-(1H-imidazol-4-yl)ethyl]iminomethyl}-5-methylphenolate are reported,viz. fac-tricarbonyl(2-{[2-(1H-imidazol-4-yl-κN3)ethyl]iminomethyl-κN}-5-methylphenolato-κO)rhenium(I) methanol monosolvate, [Re(C16H14N3O4)(CO)3]·CH3OH, (I), andfac-tricarbonyl(2-{[2-(1H-imidazol-4-yl-κN3)ethyl]iminomethyl-κN}-5-methylphenolato-κO)manganese(I),fac-[Mn(C16H14N3O4)(CO)3], (II), display facial coordination in a distorted octahedral environment. The crystal structure of (I) is stabilized by O—H...O, N—H...O and C—H...O hydrogen-bond interactions, while that of (II) is stabilized by N—H...O hydrogen-bond interactions only. These interactions result in two-dimensional networks and π–π stacking for both structures.

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.

In the centrosymmetric title compound, [Ni(C7H6FN2O2)2(H2O)2], the NiIIcation is in a slightly distorted octahedral environment and is surrounded by four O atoms from the N—O groups of the organic ligands [Ni—O = 2.0179 (13) and 2.0283 (12) Å], and two water molecules [Ni—O = 2.0967 (14) Å]. TheN-(2-fluorobenzyl)-N-nitrosohydroxylaminate monoanions act as bidentate chelating ligands. In the crystal, the Ni cations in the columns are shifted in such a way that the coordinated water molecules are involved in the formation of hydrogen bonds with the O atoms of the organic species of neighbouring molecules. Thus, a two-dimensional network parallel to (100) is built up by hydrogen-bonded molecules.
