4(4-Nitrophenyl-zao)-2-(2-Methoxy phenimino)-phenol and its coordination compounds with Ni(II), Cu(II), Co(II) and Fe(III) have been synthesized and characterized by elemental analyses, FT-IR, Far-IR, Near IR, UV-Vis, mass spectrometry and molar conductivity and their electrochemical behaviours are reported.

The principal aim of our research was to develop theoretical models for estimating stability constants of coordination compounds, focusing on chelates of heavy metals, Cu(II) and Ni(II), with bioligands (amines, amino acids and peptides). We tried to solve the problem using graph-theoretical models. We also encountered a specific problem for coordination compounds--the choice of the constitutio...

The compounds containing the complex ion or complex molecule in which central metal atom or ion is surrounded by a number of oppositely charged ions or molecules are known as co-ordination compounds [1], complex compound or simply complex. Coordination basically refers to the "coordinate covalent bonds" (dipolar bonds) between the ligands and the central atom in 1914, when first coordination co...

The structure of a glass obtained by the melt quenching of a two-dimensional (2D) coordination network was examined. X-ray analyses disclosed a 2D-to-0D structural transformation before and after glass formation. The mechanism is unique to coordination compounds, as it is characterized by labile and flexible coordination bonds.

The melt-phase synthesis of dioctyltin (IV) and triphenyltin (IV) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (IV) compounds.The reagents were ground together in a mortar and fed into a boiling glass tube. A cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. A syringe ensureda continuous flow of d...
