A ferrimagnet with a 3D molecular network (depicted) has been synthesized and characterized. The compound is composed of units of mixed‐valence Mn 4 clusters, a unit that is well known for its single‐molecule magnet properties, and Mn II paramagnetic units. Both building blocks are linked by a dicyanamide bridging ligand to form a covalently bonded three‐dimensional network. The compound becomes a ferrimagnet at 4.1 K that exhibits a spin‐flip phenomenon under the influence of a magnetic field.
