The title compound, [Mn2(C16H12Br2N2O2)2O], is an unusual dinuclear manganese(III) complex. Each MnIII ion has a distorted square-pyramidal coordination geometry. In the basal plane, the Mn atom is coordinated by two N atoms and two O atoms of the Schiff base ligand. The apical position is occupied by a bridging O2− ion, which links to the other MnIII ion in the complex; this bridging O atom lies on a twofold rotation axis.

In the title dioxidovanadium complex, [V(C13H17N2O)O2], the VVatom is in a square-based pyramidal coordination: the basal plane is defined by the phenolate O, imine N and amine N atoms of the tridentate Schiff base ligand, and by one oxide O atom. The apical position is occupied by the other oxide O atom. In the crystal, molecules are connected by N—H...O and N—H...(O,O) hydrogen bonds, forming a tetramer.

The title compound, [Cu2(OH)2(C6H16N2)2(H2O)](BF4)2, consists of dinuclear centrosymmetric [Cu2(OH)2(tmen)2(H2O)]2+ complex cations (tmen = N,N,N′,N′-tetramethylethane-1,2-diamine) and tetrafluoridoborate anions. In the cation, the CuII atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of μ-OH− anions and by the N atoms of a chelate tmen ligand in the basal plane. The apical position is statistically occupied by the O atom of a half-occupancy water molecule. The F atoms of the anion are disordered over three sets of sites with occupancies of 0.598 (9):0.269 (6):0.134 (8). The crystal packing is governed by ionic forces as well as by O—H...F hydrogen bonds.

The title compound, [Ni(C23H17N4O)(N3)], was obtained by the reaction of the Schiff base ligand 2-[(tri-2-pyridylmethyl)iminomethyl]phenol with sodium azide and nickel(II) perchlorate in methanol solution. The NiII atom is four-coordinated by the phenolate O, the imine N and a pyridine N atom of the Schiff base ligand, and by the terminal N atom of an azide ligand, forming a square-planar geometry. The other two pyridyl rings are oriented at an angle of 72.29 (11)° to each other.

The title compound, [Ni(C18H18N2O4)]·CHCl3, has been synthesized by the solid-state reaction of Ni(OAc)2·4H2O and the Schiff base ligand N,N′-ethylene-bis(3-methoxysalicylaldehyde) [abbreviated as H2(3-MeO-salen)]. The Ni atom adopts a slightly deformed square-planar coordination geometry in which the 3-MeO-salen ligand acts as a cis-N2O2 donor.

In the title compound, [Cu(C19H16Br4N2O2)], the CuIIion and the substituted C atom of the diamine fragment lie on a crystallographic twofold rotation axis. The geometry around the CuIIion is distorted square-planar, which is defined by the N2O2donor atoms of the coordinated Schiff base ligand. The dihedral angle between the symmetry-related substituted benzene rings is 25.33 (14)°. The crystal structure is stabilized by an intermolecular π–π interaction [centroid–centroid distance = 3.8891 (18) Å].

The title compound, {[Zn(C9H11N2S2)2]·0.5C6H7N} n , comprises two independent, but chemically similar, Zn[S2CN(Et)CH2py]2 residues and a 4-methylpyridine solvent molecule in the asymmetric unit. The Zn-containing units are connected into a one-dimensional coordination polymer (zigzag topology) propagating in the [010] direction, with one dithiocarbamate ligand bridging in a μ2-κ3 mode, employing one pyridyl N and both dithiocarbamate S atoms, while the other is κ2-chelating. In each case, the resultant ZnNS4 coordination geometry approximates a square pyramid, with the pyridyl N atom in the apical position. In the crystal, the chains are linked into a three-dimensional architecture by methyl- and pyridyl-C—H...S, methylene-C—H...N(pyridyl) and pyridyl-C—H...π(ZnS2C) interactions. The connection between the chain and the 4-methylpyridine solvent molecule is of the type pyridyl-C—H...N(4-methylpyridine).

The mononuclear TiIVtitle complex, [Ti(C28H22N2O2)(C3H7O)2]·0.5C6H14, crystallizes as ann-hexane hemisolvate. The TiIVatom is coordinated by a dianionic tetradentate biphenyl Schiff base ligand and two O atoms of two propan-2-olate anions in a distorted TiN2O4octahedral coordination geometry, in which the two N atoms are in acisconfiguration. In the crystal, complex molecules are stacked parallel to [100], leaving space for channels parallel to [001] where the solvent molecules are located.
