Synthesis and Characterization of Two Dimensional Metal Organic Framework of Cerium with Tetraaza Macrocyclic.

A two dimensional metal organic framework containing cerium sufate layers and ethylenediaminium between layers was obtained by refluxing the mixture of cerium sulphate and 5,5,7,12,12,14-hexamethyl-1,4,8,11- tetraazacyclotetradeca-7,14-diene bromide. The complex was characterized by infrared spectroscopy and microelemental analysis. X-ray study showed that the complex adopts eleven coordination environments about the central atom. Thermogravimetric study showed the removal of water molecules at about 70 °C followed by a gradual mass loss until the whole structure collapsed at about 400 °C. [ABSTRACT FROM AUTHOR]
