Stuck in the middle with you : The spherical cluster {(Mo)Mo 5 } 12 Cr 30 ( 1 ) fills, with its spin, a gap in the series of the analogous Fe ( S =5/2) and V ( S =1/2) clusters. This allows a deeper understanding of the magnetic properties of the series members, particularly with reference to geometric frustration, also found in the famous Kagomé lattices. The spherical clusters can be considered as coordination polymers with spherical periodicity which contain unique pentagonal molybdenum oxide based ligands.
