文摘

Metal carbonyl complexes have been widely investigated for use in heterogeneous catalysis as a method for the formation of metal clusters. However, their use as a metal source for metallosupramolecular assemblies has not been widely considered. In this study, the combination of Cr(CO)₆ with p-terphenyldinitrile on Au(111) creates ordered 1D chains, which are thermally stable up to 423 K. The bond between the nitrile linkers and metal nodes undergoes a unique π-interaction, which thus far has been observed only in a small set of organometallic complexes. The structure and composition of the metal–organic coordination network have been elucidated and characterized using scanning tunnelling microscopy, high-resolution electron energy loss spectroscopy, and density functional theory calculations.
