<div>We introduce a dataset of 24 interaction energy curves of open-shell noncovalent dimers, referred to as the O24x5 dataset. The dataset consists of high-spin dimers up to eleven atoms selected to assure diversity with respect to interactions types: dispersion, electrostatics and induction. The benchmark interaction energies are obtained at the restricted open-shell CCSD(T) level of theory with complete basis set extrapolation aug-cc-pVQZ--> aug-cc-pV5Z.</div>
