异构的

First, ab initio calculations have been performed at the HF/6-31G level of theory for 27 indazolyl urea compounds (using 1H-indazole tautomeric form). On the basis of optimized structures, five kinds of topological indices, electrostatic potentials as well as their statistically-drived quantities have been obtained.
