title: DFT calculations on [6.8]cyclacenes and CpCo-capped [4.8]cyclacenes.
abstract: Two different types of cyclacenes, utilizing eight-membered and six-/four-membered rings as building blocks ([6.8](n) and CpCo-capped [4.8](n)cyclacenes), have been theoretically investigated with respect to their geometries, relative energies, and magnetic properties (aromaticity).
