Structures, energies, and vibrational frequencies have been calculated for two C 30 H 20 isomers with a dodecahedrane cage and two pentaprismane cages at the B3LYP/6‐31G* level of theory. Thus, two C 30 H 20 isomers have the form of coplanar tri‐cage molecules. The symmetry of one C 30 H 20 isomer is of D 5 d and that of another is of C 2 V . The heat of formation for two C 30 H 20 isomers have been estimated. Heats of formation of two C 30 H 20 isomers as well as the vibrational analysis indicate that two C 30 H 20 isomers enjoy sufficient stability to allow for its experimental preparation. © 2004 Wiley Periodicals, Inc.
