The resulting odd number of intermolecular bonds induces an unpaired $\\pi$-electron and hence a quantised magnetic moment in otherwise non-magnetic nanoribbons. We further reveal the formation of an antiferromagnetic ground state upon the linear arrangement of spin-1/2 C$_{60}$ cages that is insensitive to the specific structural motifs.
