Many strategies have emerged in recent years in the quest to design and synthesize functional materials which show cooperative properties. A particularly successful route to new materials is the self-assembly of molecular building blocks (or synthons) which link paramagnetic metal ions. These compounds frequently have low-dimensional structural motifs which drive magnetic interactions in one or two dimensions. A significant recent advance in this area has been the successful use of hydrogen bonds to organize synthons into patterned networks. By exploiting these relatively weak intermolecular interactions it is possible to organize the positions of molecules and tune the dimensionality and related properties of a system. Here we propose to study the magnetic order and dynamics in three new molecular magnets where this philosophy has been employed to create novel molecular architectures.
