In the title complex, [ZnI(2)(C(14)H(21)BrN(2)O)]·CH(3)OH, the asymmetric unit consists of a mononuclear zinc(II) complex mol-ecule and a methanol solvent mol-ecule. The compound was derived from the zwitterionic form of the Schiff base 4-bromo-2-[3-(diethyl-amino)propyl-imino-meth-yl]phenol. The Zn(II) atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand and by two iodide ions in a distorted tetra-hedral coordination. In the crystal structure, the methanol mol-ecules are linked to the Schiff base mol-ecules through N-H⋯O and O-H⋯O hydrogen bonds. One I atom is disordered over two positions in a 0.702 (19):0.298 (19) ratio.

The well-known inhibitory strength of 3d metal Schiff base complexes against urease enzymes has long been acknowledged, but their untapped potential to act as ureolytic mimics of active metallobiosites remained unexplored. To break the new ground, we present pyrrolidine-based mononuclear Ni(II)-azide complex {[NiL(HL)(N)]·1.5(HO)} using the N,N,O donor ligand, namely ()-4-bromo-2-(((2-(pyrrolidin-1-yl)ethyl)imino)methyl)phenol.

The asymmetric Schiff base prepared from ethylenediamine and pyridine-2-carboxaldehyde reacts with Fe(ClO)·6HO to form the Fe(II) complex [FeL](ClO) with L = ,-diethyl-'-(pyridin-2-yl)methylene)ethane-1,2-diamine, where the Fe(III) starting material has been unexpectedly reduced to Fe(II). This complex was characterized by elemental analysis, infrared spectra, single crystal and powder X-ray diffraction measurements, variable temperature DC magnetic measurement and room temperature Mössbauer spectroscopy. The asymmetric ligand L coordinates in a tridentate fashion through its pyridyl, azomethine and amino nitrogen atoms, generating a distorted octahedral geometry around the central metal ion.

Air-stable single-molecule magnets (SMMs) can be obtained by confining Dy ion in a coordination environment; however, most of the current efforts were focused on modifying the rigidity of the macrocycle ligand. Herein, we attempt to assemble air-stable SMMs based on macrocycles with a replaceable coordination site. By using an in situ 1 + 1 Schiff-base reaction of dialdehyde with diamine, three air-stable SMMs have been obtained in which one of the equatorial coordination sites can be varied from -NH- (for ), -O- (for ), and -NMe- (for ).
