AbstractScanning tunneling microscopy has been used to investigate the structural characteristics of thin film dimolybdenum tetracetate on single crystal graphite and molybdenum disulphide substrates. The results indicate that the observed surface structures of the films correspond to two-dimensional crystal faces of the three-dimensional X-ray crystal structure of dimolybdenum tetraacetate. The electronic structure of the films was investigated using photoelectron spectroscopy and correlated to the observed surface structures. Furthermore, thin films of dichromium tetraacetate as well as mixed films of the two dimers on graphite and molybdenum disulphide were also investigated by valence photoelectron spectroscopy.
