By combining open-shell transition metal ions with suitable organic linkers flexible building block systems may be produced for generating novel classes of materials, especially quantum magnets with distinct exchange-coupling topologies. A particularly interesting feature of these molecule-based magnets is their small exchange coupling constants J, weak enough for laboratory magnets to drive the systems into the interesting high-field regime where gµBB > J. In this contribution we will discuss various realizations of molecule-based low-dimensional quantum magnets such as Cu(II) cyclosiloxanolate complexes or a Cu(II) coordination polymer. The latter system can be used to study generic magnetocaloric and magnetoelastic properties of the antiferromagnetic S = 1/2 Heisenberg chain near the saturation field.
