Today's perpetual need for technology miniaturization necessitates the design of hybrid materials possessing multiple functionalities. Along these lines, we have been investigating a building block approach for introducing additional properties to molecular magnets. With the use of coordination chemistry we were able to build different novel architectures from these zero-dimensional systems, namely the archetypical Mn₁₂ single molecule magnet (SMM). The linkers of choice were neutral diols, and we have investigated bridges with a range of backbone rigidity and size. This investigation resulted in different Mn₁₂-SMM chains, oligomers, and networks, while all the materials were characterized with x-ray crystallography, SQUID magnetometry, and high-field/frequency EPR spectroscopy.
