Caption: Figure 10.
Calculated spin densities (isovalue 0.005 e/Å3) of (a) Fe13 (Ms = 45), (b) Fe13–C2H2 (Ms = 41), and (c) Fe13–(C2H2)6 (Ms = 35). Vermilion represents up (﹩\uparrow ﹩) and sky blue represents down (﹩\downarrow ﹩) spins. The down (﹩\downarrow ﹩) spin-density localized on the central Fe atom in the Fe13 cluster is delocalized on the carbon atoms of C2H2 in Fe13–C2H2 and Fe13–(C2H2)6.
