Structural, Spectroscopic Characterization and Application of a Co(II) Coordination Polymer [Co(suc)(bpm)] ⋅ 2H₂O

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 antiferromagnetic (AF) exchange interactions were evinced by Curie Constant (C)=1.803 cm3mol−1K 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.
