Thermal, spectral and magnetic studies of some first row transition metal complexes of 1,4-bis(4-aminocyclohexyl) butadiyne

Add time:07/13/2019    Source:sciencedirect.com

Some new compounds of l,4-bis(4-aminocyclohexyl) butadiyne with cobalt(II), nickel(II) and copper(II) have been prepared in ethanolic solution. The compounds which have been characterised by analyses, magnetic moments, vibrational and electronic spectra, have polymeric octahedral structures. The thermal behaviour of these compounds has been studied by thermogravimetry (TG) and differential scanning calorimetry (DSC) techniques. Thermal decomposition studies show that the hydrated compounds lose water followed by organic ligand to give the metal oxide, while the anhydrous compounds lose organic ligand to give the metal oxide. (The crystal structure of 1,4-bis(4-aminocyclohexyl) butadiyne is also discussed.)
