Six solid energetic complexes,M(ATZ)(bpy)m·nH2O((1)M=Mn,m=2,n=3;(2)M=Co,m=2,n=7;(3)M=Ni,m=2,n=0;(4)M=Cu,m=1,n=0;(5)M=Pb,m=1,n=3;(6)M=Zn,m=1,n=1;ATZ=5,5''-azotetrazole,bpy=2,2'-bipyridine),were synthesized and characterized.The enthalpy changes of the liquid phase reactions,ΔrHmθ,investigated by microcalorimetry,were ΔrHmθ(1)=-241.245±0.060 kJ/mol,ΔrHmθ(2)=-256.875±0.050 kJ/mol,ΔrHmθ(3)=-265.172±0.038 kJ/mol,ΔrHmθ(4)=-236.538±0.038 kJ/mol,ΔrHmθ(5)=-249.698±0.038 kJ/mol,ΔrHmθ(6)=-185.072±0.048 kJ/mol,respectively.In addition,thermokinetics of the liquid phase formation reactions was studied,and the activation enthalpy(ΔH≠θ),the activation entropy(ΔS≠θ),the activation free energy(ΔG≠θ),the apparent reaction rate constant(k),the apparent activation energy(E),the pre-exponential constant(A),and the reaction order(n) were calculated by the combination of the thermochemical data of the reaction and kinetic equations with the data of thermokinetic experiments,which will supply the necessary thermodynamic data for the application of these complexes.
