Abstract:The specific heat capacity of four carbohydrazide nitrate energetic coordination compounds ［M(CHZ)3］(NO3)2,(M=Mn,Co,Zn,Ni) were determined by differential scanning calorimeter (DSC) under a temperature range,and regression equations for the specific heat capacity changing with temperature were obtained by Origin 7.0. The equations of Ni(CHZ)3(NO3)2 and Mn(CHZ)3(NO3)2 are functions of sixth degree,second degree and third degree in some range of temperature,equations of the others mostly are functions of fourth degree or fifth degree,where the relative coefficient square is more than 0.987,and standard deviation is smaller than 0.017. Except Zn(CHZ)3(NO3)2,the specific heat capacity of the compounds changes more,and one or more peaks appear in the curves of the specific heat capacity. TG and FTIR were carried through. At 200 ℃,only Co(CHZ)3(NO3)2 loses 8.64% of its mass. As FTIR spectra are not same at different temperature,it is possible that the crystal transformation results in the change of the specific heat capacity.
