Summary
Researchers synthesized novel mononuclear clusterfullerenes (MNC@C76) that stabilize strained structures, enabling single-atom properties. One such molecule, TbNC@C76, exhibits single-molecule magnet behavior.
Area of Science:
- Fullerene chemistry
- Supramolecular chemistry
- Materials science
Background:
- Fused-pentagons in fullerenes cause steric strain, often requiring multiple metals for stabilization.
- Existing non-IPR clusterfullerenes necessitate multi-metal clusters, hindering single-atom property exploration.
Purpose of the Study:
- To synthesize and isolate novel non-IPR mononuclear clusterfullerenes (MNC@C76) with M=Tb and Y.
- To stabilize strained fused-pentagons using a single metal cluster.
- To investigate the structural and magnetic properties of these new clusterfullerenes.
Main Methods:
- Synthesis and isolation of MNC@C76 (M=Tb, Y).
- Single-crystal X-ray diffraction for unambiguous structure determination.
- Magnetic property measurements.
Main Results:
- Successful synthesis of non-IPR mononuclear clusterfullerenes MNC@C76 (M=Tb, Y).
- Structure determination revealed a non-IPR C2v(19138)-C76 cage encapsulating a nearly linear MNC cluster.
- TbNC@C76 demonstrated field-induced single-molecule magnet (SMM) behavior.
Conclusions:
- Mononuclear clusters can stabilize strained fused-pentagons in non-IPR fullerenes.
- The novel MNC@C76 structures offer a new platform for studying single-atom properties.
- TbNC@C76 represents a promising candidate for single-molecule magnet applications.

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
