The standard enthalpies of combustion and formation of crystalline cobalt tetrakis(4-metoxyphenyl)porphin complex

The energy of combustion of cobalt tetrakis(4-metoxyphenyl)porphin was determined in an isothermic-shell liquid calorimeter with a stationary calorimetric bomb. The standard enthalpies of combustion and formation of the complex were calculated, −Δ _c H ^o = 27334.06 ± 50.98 kJ/mol and Δ_f H ^o = 3062.90 ± 50.97 kJ/mol. Original Russian Text ? R.P.
