Abstract
A Co(II)coordination polymer[Co(suc)(bpm)]·2H2O(1)built from succinate(suc)and bipyrimidine(bpm)is synthesized hydrothermally and characterized by different methods.It crystallizes in a monoclinic space group P21/n with an intriguing 3D polymeric architecture.The weak antiferromag-netic(AF)exchange interactions were evinced by Curie Constant(C)= 1.803 cm~3mol~(-1)K and a negative Weiss constant(φ)= 30.163 K.Type VI adsorption isotherm behavior of 1 at 77 K revealed its non-porous property.Compound 1 was investigated and successfully utilized as an additive in lowering the decomposition temperature of ammonium nitrate(AN)based fuels as demonstrated from TG and DSC experiments performed in nitrogen atmosphere.
