Abstract:
Through a careful design of the molecular precursor we have successfully constructed the metal-organic Sierpiński triangles on Au(111) via on-surface coordination chemistry, which is demonstrated by the interplay of high-resolution STM imaging and DFT calculations. The coordination Sierpiński triangles show high stabilities as evidenced by room temperature STM imaging, and could withstand a thermal treatment up to 450 K.

Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
