Single-molecule magnets (SMMs) are compounds displaying slow relaxation of their spin magnetization with potential applications in high-density data storage and spintronics. Coordination polymers with SMM properties provide necessary structures for scaling the magnets to the macroscopic level. Homochiral (M)- or (P)-Co(SO4)(1,3-bbix)(H2O)3 (1M or 1P) (1,3-bbix = 1,3-bis[(1H-benzo[d]imidazol-1-yl)methyl]benzene) have shown SMM properties. We have probed the magnetic properties of 1M by far-IR magneto-spectroscopy (FIRMS), high-frequency/field EPR (HFEPR), pulsed EPR, and ab initio calculations, leading to the determination of zero-field splitting (ZFS) parameters (axial D and rhombic E) as well as spin-lattice and spin-spin relaxation times (T1 and T2).
