The C24 is one of the small fullerenes which has many structures. Between these structures twoisomers are more common. One of the isomers has six 4-member rings and eight 6-member rings (6-4) andanother has two 6-member rings and twelve 5-member rings (6-5). In this article the structure and stability ofthese isomers were studied using Gaussian 09 package. The result of energy calculates shown that C24 (6-5)isomer has lower energy that means more stability. Also calculation of Free energy and Enthalpy provedsame results. In the calculation of electrical properties, the 6-5 isomer has lower Eg that cause moreconductivity.
