Arylazoimidazoles are important dyes which were intensively studied in the past. In contrast, triarylazoimidazoles (derivatives which carry aryl substituents at the imidazole core) received almost no attention in the scientific literature. Here, we report a new family of simple and easily accessible triarylazoimidazole-group 12 metal complexes, which feature highly efficient photo-luminescence emission (Φ up to  0.44). Novel compounds exhibit bright red emission in solution, which could be excited with a visible light.

Post-synthetic modification of metal–organic frameworks (MOFs) facilitates a strategic transformation of potentially inert frameworks into functionalized materials, tailoring them for specific applications. In particular, the post-synthetic incorporation of transition-metal complexes within MOFs, a process known as ‘metalation’, is a particularly promising avenue towards functionalizing MOFs. Herein, we describe the post-synthetic metalation of a microporous MOF with various transition-metal nitrates. The parent framework, 1 , contains free-nitrogen donor chelation sites, which readily coordinate metal complexes in a single-crystal to single-crystal transformation which, remarkably, can be readily monitored by X-ray crystallography. The presence of an open void surrounding the chelation site in 1 prompted us to investigate the effect of the MOF pore environment on included metal complexes, particularly examining whether void space would induce changes in the coordination sphere of chelated complexes reminiscent of those found in the solution state. To test this hypothesis, we systematically metalated 1 with first-row transition-metal nitrates and elucidated the coordination environment of the respective transition-metal complexes using X-ray crystallography. Comparison of the coordination sphere parameters of coordinated transition-metal complexes in 1 against equivalent solid- and solution-state species suggests that the void space in 1 does not markedly influence the coordination sphere of chelated species but we show notably different post-synthetic metalation outcomes when different solvents are used. This article is part of the themed issue ‘Coordination polymers and metal–organic frameworks: materials by design’.

In currenttask, β-dike tone ligand mixed with different metal nitrates and form different metal complexes such as Ni(II), Fe(III), Cr(III). Ligand gives tautomerism, this tautomerism process was examined with the help ofFTIR.Because of enol assist as ligand in the metal complexes preparation. The preparedmetal complexearede scribed by various techniques like elemental analysis, FTIR, DTA, TGA, magnetic properties and molar conductivities. Different properties of complexes are studied such as antioxidant, antibacterial, anti-inflammatory and anti fungal properties.

A new series of 10-membered tellurium containing tetraazamacrocyclic complexes, [ML1Cl2], [ML2Cl2] and [ML3Cl2], where [M=Zn(II), Cd(II), Hg(II); L1, L2and L3=10-membered tellurium containing tetraazamacrocyclic ligands] have been prepared via the template condensation of ethylenediamine and diaryltellurium dichlorides, R2TeCl2, (R=p-hydroxyphenyl, 3-methyl-4-hydroxyphenyl,p-methoxyphenyl) in the presence of metal chlorides. These complexes have been characterized by elemental analyses, conductivity measurements, infrared, electronic absorption and proton magnetic resonance spectral studies. IR and PMR spectra confirm the formation of 10-membered tetraazamacrocycle skeleton and their tetradentate nature. An octahedral geometry has been assigned to all the metal complexes on the basis of various physicochemical studies.
