    • The relation between the cluster size and the value of the corresponding HOMO-LUMO gap has been investigated theoretically in several systems, e.g. Mg clusters [11]. With increasing cluster size the HOMO-LUMO gap decreases. However, the value for the gap does not have to follow a strictly linear course.

    • The third potential bond, Cu15-Se1, 311.4 pm, is too long for a covalent bond. Cu15 is, strictly speaking, twofold coordinated with an Se 2-Cu 5-Se5 angle of 138.4°. The sum of the angles around this metal atom, taking the Cu15-Se1, into account is 338.6 (and thus clearly deviates from planarity). Also the Cu18 trigonal environment is no longer planar. The sum of the Se-Cu-Se angles around copper is 338.6°.
