A solvothermal reaction of Co(CH 3 COO) 2 ·4H 2 O and 5-mercapto-1-methyl-tetrazole (Hmmtz) in methanol (MeOH) yielded a one-dimensional solvent-free energetic coordination polymer, namely, [Co(mmtz) 2 ] n 1 , which was structurally characterized. The enthalpy of formation (Δ f H °) of 1 (907 kJ mol -1 ) is much larger than that of commercial 2,4,6-trinitrotoluene (-59 kJ mol -1 ). The impact sensitivity and the friction sensitivity are greater than 40 J and 360 N, respectively, indicating that compound 1 exhibits a potential application as a safe explosive. Temperature-dependent molar magnetic susceptibilities show that weak antiferromagnetic behavior exists in 1 .
