|Title:||Synthesis, characterization and thermal behavior of 18 cadmium halides adducts involving ethyleneurea, ethylenethiourea and propyleneurea|
|Author:||de Farias, RF|
|Abstract:||In this work we report on the synthesis, characterization and thermal behavior of 18 adducts of general formula CdX2.nL (where X = Cl, Br and I, n = 1 and 2, and L = ethyleneurea (eu), ethylenethiourea (etu) and propyleneurea (pu)). The IR spectroscopy results shows that for the eu and pu adducts, coordination occurs through oxygen, whereas for etu, nitrogen is used as coordination site. The thermogravimetric curves shows that the synthesized adducts releases the ligand molecules in a single mass loss step, In considering adducts with same stoichiometry, the observed thermal stability trend is etu > pu > eu.
