In a novel molecular beam experiment we have calorimetrically investigated
the dependence of the formation energies of isolated SnN clusters
on their size. The experimentally determined size dependence of the
formation energy for SnN clusters consisting of between 95 and 975
atoms can be explained by the existence of two different types of
cluster isomers: One class of isomers is characterized by formation
energies proportional to N-1/3, indicating compact spherical-like
shapes. The other class has constant formation energies for the investigated
size range, which is consistent with quasi-one-dimensional geometries.
