N2 - A quaternary chalcogenide (Formula presented)(Formula presented), which consists of [(Formula presented)(Formula presented)(Formula presented) tetrameric clusters linked by sharing their terminal sulfur atoms to form a quasi-two-dimensional structure, exhibits magnetic properties which can be explained by a model containing no exchange coupling between neighboring clusters. To explain this result we calculated the Coulomb energy of different configurations of (Formula presented) and (Formula presented) ions. These calculations clearly showed that the lowest energy configurations occurred when the distribution of (Formula presented)/(Formula presented) ions in each cluster was such that no (Formula presented) was magnetically coupled to a (Formula presented) in an adjacent cluster through a sulfur bond, in agreement with the magnetic analysis.
