A structural model is proposed for a Si cluster of 45 atoms, a size observed experimentally to be chemically non-reacti\,e. The model closely resembles surface reconstructions of bulk Si and consists of a core of fourfold coordinated atoms surrounded by xbonded chains. The stability of the cluster a
