Abstract

Scanning tunneling microscopy (STM) has been used to study phosphotungstic acid and rhenium carbonyl cluster complexes adsorbed on graphite. For phosphotungstic acid, cluster formation is observed as well as short-range (4-A period) and long-range (110-A period) hexagonal ordering. Acetone spun films of [Et4N]3[Re7C(CO)2J on graphite exhibit two distinct nongraphitic periodicities. One of these is rowlike and associated with an adsorbed acetone monolayer (4-A period), and the other, which is hexagonal (10-A period), represents an array of individual metal cluster molecules. In a separate effort, STM has been used to study the sliding charge-density wave (CDW) material NbSe3in its room-temperature non-CDW state in order to obtain structural information which can be correlated with low-temperature, CDW-state studies. The unit-cell features and quasi-one-dimensional chainlike structure are readily observed.
