Metal-organic complexes were formed by means of inelastic excitations in a scanning tunneling microscope (STM). The electronic structure of the complex was characterized using STM imaging and spectroscopy. By exploiting the symmetry of the complex, its electronic structure can be rationalized from linear combinations of molecular orbitals. The actual bonding geometry, which cannot be inferred from STM alone, was determined from atomic force microscopy images with atomic resolution. Our study demonstrates that the combination of these techniques enables a direct quantification of the interplay of geometry and electronic coupling in metal-organic complexes in real space.
采用扫描隧道显微镜（STM）中的非弹性激发形成了金属有机配合物。使用 STM 成像和光谱学对配合物的电子结构进行了表征。通过利用配合物的对称性，可以从分子轨道的线性组合来合理化其电子结构。实际的键合几何形状，单凭 STM 无法推断，而是从具有原子分辨率的原子力显微镜图像确定的。我们的研究表明，这些技术的结合能够直接量化金属有机配合物中几何形状和电子耦合在实空间中的相互作用。
