Two new coordination polymers with the general formula {[(ML)-L-II]center dot xsolvent}(n), in which M-II = Fe, Co, have been prepared solvothermally and characterized. The compounds exhibit isostructurality with different solvents and show similarities with our previously reported homo- and heteronuclear coordination layers. Photoluminescence study shows that some of the compounds exhibit high photoluminescence intensities. Density functional theory calculations reveal that the properties of the coordination polymers significantly depend on the nature of the metal ions.
Two new 2,6-diacetylpyridine bis(nicotinoylhydrazone) coordination polymers with the general formula {[(ML)-L-II]center dot xsolvent}(n), in which M-II = Fe, Co, were prepared solvothermally and characterized by various methods. Both compounds exhibit isostructurality with different solvents with our previously reported homo- and heteronuclear coordination layers (M-II = Mn, Zn, Cd, MnZn, Zn0.75Cd1.25). A comprehensive investigation of the isometricity revealed the existence of a high degree of similarity for five pairs, medium similarity for six pairs, and low similarity for ten pairs. Despite the fact that the Mn(ii) and Zn(ii) coordination polymers are isostructural to each other, they are enantiomers of other compounds. The photoluminescence study was performed on all seven compounds and some of them were found to exhibit high photoluminescence intensities. Density functional theory has been used to estimate the nonlinear optical and thermoelectric properties of the given series of coordination polymers. It has been shown that, regardless of the different degrees of isostructurality of the studied coordination polymers, their properties significantly depend on the nature of the metal ions.
