用扫描隧道显微镜研究了铁(II)自旋交叉络合物Fe(1，10-邻菲咯啉)(2)(NCS)(2)，称为Fe-phen，它吸附在Au(111)的人字形重建表面上，形成亚单分子层。Fe-phen分子通过它们的NCS-基团仅与重构表面的面心立方结构域的Au原子结合，从而提升了人字形重构。分子堆叠在一起形成一维链，沿着Au[110]方向延伸。相邻的Fe-phen分子之间的距离约为2.65 nm，相当于该方向上的9个原子间距。由两个邻菲咯啉基团定义的分子轴垂直于链轴排列，沿着Au 221在条上方
The iron(II) spin crossover complex Fe(1,10-phenanthroline)(2)(NCS)(2), dubbed Fe-phen, has been studied with scanning tunneling microscopy, after adsorption on the 'herringbone' reconstructed surface of Au(111) for sub-monolayer coverages. The Fe-phen molecules attach, through their NCS-groups, to the Au atoms of the fcc domains of the reconstructed surface only, thereby lifting the herringbone reconstruction. The molecules stack to form 1D chains, which run along the Au[110] directions. Neighboring Fe-phen molecules are separated by approximately 2.65 nm, corresponding to 9 atomic spacings in this direction. The molecular axis, defined by the two phenanthroline groups, is aligned perpendicular to the chain axis, along the Au 221 over bar
