The title compound, [Mn2(C7H4NO4)4(C6H7N)4] or [Mn2(μ-NBz)2(κ2-NBz)2(4-Mepy)4], where NBz is 4-nitrobenzoate and 4-Mepy is 4-methylpyridine, is a centrosymmetric dinuclear complex in which the MnIIatoms are bridged by two NBz ligands with Mn...Mn = 4.1324 (4) Å. The MnIIatom in this dimeric species is present in a distorted octahedral environment with the four coordinating O atoms forming the equatorial plane and the two pyridyl N atoms occupying the axial sites. An important structural feature of the dimeric complex is that each of the bridging carboxylate ligands binds to the metal ions in an asymmetric fashion involving bent and linear Mn—O—C units. The crystal packing is consolidated by C—H...O and C—H...π interactions.

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 title compound, [Zn(C20H16N3S2)2]·CH3CN, two different Schiff base moieties coordinate to the central ZnIIion as tridentateN,N′,S-chelating ligands, creating a distorted octahedral environment [the smallest angle being 73.24 (6)° and the widest angle being 155.73 (7)°], with the two S atoms incispositions. The dihedral angle between the mean planes of the two coordinating ligands is 83.65 (5)°. The crystal packing is consolidated by weak C—H...N hydrogen-bonding interactions.

In the crystal structure of the mononuclear title compound, [Mn(NCS)2(C10H8N2)2]·C10H8N2, the MnIIcation is coordinated in an all-cisconfiguration by two N-bound thiocyanate anions and two 2,2′-bipyridine ligands within a slightly distorted octahedral environment. The asymmetric unit consists of one MnIIcation, two thiocyanate anions and two 2,2′-bipyridine ligands, as well as two non-coordinating 2,2′-bipyridine ligands that are each located on centres of inversion. In the crystal structure, the discrete [Mn(NCS)2(C10H8N2)2] complex molecules are arranged in such a way that cavities are formed, in which the solvent 2,2′-bipyridine molecules are located. Apart from van der Waals forces, there are no remarkable intermolecular interactions present in the crystal structure.

The title compound, [Ni(C6H4NO2)2(C16H38N6)], was prepared through self-assembly of a nickel(II) azamacrocyclic complex with isonicotinic acid. The NiIIatom is located on an inversion center and exhibits a distorted octahedral N4O2coordination environment, with the four secondary N atoms of the azamacrocyclic ligand in the equatorial plane [average Ni—Neq= 2.064 (11) Å] and two O atoms of monodentate isonicotinate anions in axial positions [Ni—Oax= 2.137 (1) Å]. Intramolecular N—H...O hydrogen bonds between one of the secondary amine N atoms of the azamacrocyclic ligand and the non-coordinating carboxylate O atom of the anion stabilize the molecular structure. Intermolecular N—H...N hydrogen bonds, as well as π–π interactions between neighbouring pyridine rings, give rise to the formations of supramolecular ribbons extending parallel to [001].

In the title compound, [Cu(ClO4)2(C20H40N4)], the CuII ion has a tetragonally distorted octahedral environment, with the four N atoms of the macrocyclic ligand in equatorial positions and the O atoms of two perchlorate groups in axial positions. The CuII ion is situated on an inversion centre. The macrocyclic ligand adopts its most stable trans-III conformation. The long axial Cu—O bond is the result of the Jahn–Teller effect. The crystal structure is stabilized by intramolecular hydrogen bonds between secondary N—H and the O atoms of the perchlorate groups.

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.
