Abstract For some categories of Pt and Au cluster compounds, a simple electron count theory is successful in predicting its structure. Six or eight cluster valence electrons correspond to toroidal or spherical structures, respectively. As the characterization of more complex clusters as toroidal and spheroidal may seem to be somewhat arbitrary, an objective method for classifying the geometry is developed. From atom position coordinates, a numerical parameter can be calculated which gives unambiguous indication of the geometry. It is shown that there is a perfect correlation between this parameter and the electron count.
