The title compound, [Ni(C(4)H(13)N(3))(2)][Ni(C(4)N(2)S(2))(2)], has been synthesized by the reaction of Ni(ClO(4))(2)·6H(2)O, diethyl-enetriamine (deta) and Na(2)[Ni(mnt)(2)] [mnt = maleonitrile-dithiol-ate(2-)] in methanol. The structure is composed of a [Ni(deta)(2)](2+) cation and a [Ni(mnt)(2)](2-) anion. The coordination geometry of the Ni(II) ion in the cation is slightly distorted octa-hedral, defined by six N atoms from two deta ligands, while the Ni(II) ion in the anion is four-coordinated by four S atoms from two mnt ligands in a slightly distorted square-planar geometry. The cations and anions are connected by N-H⋯N hydrogen bonds.

A highly effective method for creating a supramolecular metallogel of Ni(II) ions (NiA-TA) has been developed in our work. This approach uses benzene-1,3,5-tricarboxylic acid as a low molecular weight gelator (LMWG) in DMF solvent. Rheological studies assessed the mechanical properties of the Ni(II)-metallogel, revealing its angular frequency response and thixotropic behaviour.

A novel nanocomposite magnetic hydrogel was synthesized based on κ-carrageenan, acrylic acid, and activated carbon as an absorbent for removing heavy metal ions from aqueous solution. FT-IR spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and vibration sample magnetometer (VSM) were employed to confirm the structure of the nanocomposite hydrogels. The effects of contact time, pH, particle size, temperature, and metal ion concentration on the metal ion adsorption were investigated.

Two artificial imidazole-derived nucleobases, Im (3H-imidazo[4,5-f]quinolin-5-ol) and Im (imidazole-4-carboxylate), were introduced into short DNA duplexes to systematically investigate their thermal stability upon metal ion coordination. Metal-mediated base pairs are formed with the 3d metal ions Co, Ni and Zn, as well as with the lanthanoid ions Eu and Sm, which induce a thermal stabilization of up to 8 °C upon binding. The latter are the first lanthanoid-mediated base pairs involving only four donor atoms that result in a significant duplex stabilization.

The Schiff base metal complexes containing the transition metal ions Co(II), Ni(II) and Cu(II) were synthesized using their nitrate and acetate salts. An octahedral environment encircling metal complexes has been demonstrated by the findings of multiple spectroscopic approaches that were employed to demonstrate the structure of the metal complexes. The Coats-Redfern method of thermal analysis was employed to carry out the kinetic and thermodynamic calculations.

The unit cell of the title compound, [Ni(CHClN)]·2CHOH, consists of a neutral complex and two methanol mol-ecules. In the complex, the two tridentate 2-(3-(4-chloro-phen-yl)-1-1,2,4-triazol-5-yl)-6-(1-pyrazol-1-yl)pyridine ligands coordinate to the central Ni ion through the N atoms of the pyrazole, pyridine and triazole groups, forming a pseudo-octa-hedral coordination sphere. Neighbouring tapered mol-ecules are linked through weak C-H(pz)⋯π(ph) inter-actions into monoperiodic chains, which are further linked through weak C-H⋯N/C inter-actions into diperiodic layers.
