This paper investigates the preparation of lanthanum metal nitrate complex of hexa- methylenetetramine in water at room temperature. This complex of molecular formulae [La (NO 3 ) 2 (H 2- O) 6 ] (2HMTA) (NO 3  ) (H 2 O) was characterized by X-ray crystallography. Thermal decomposition was investigated using TG, TG–DSC and ignition delay measurements. Kinetic analysis of isothermal TG data has been investigated using model fitting methods as well as model free isoconversional methods. The sensitivity measurements towards mechanical destructive stimuli such as impact and friction were car- ried out and the complex was found to be insensitive. In order to identify the end product of thermolysis, X-ray diffraction patterns of end product was carried out which proves the formation of La 2 O 3 . Ó 2014 Elsevier B.V.
