Intermolecular Contact-Tuned Magnetic Nature in One-Dimensional 3d−5d Bimetallic Systems: From a Metamagnet to a Single-Chain Magnet

Assembling [W(CN)6(bpy)]− and magnetic anisotropic Mn Schiff bases produced two MnIII(3d)−WV(5d) bimetallic chains. Modulation of the types and degrees of interchain π−π interactions in the one-dimensional coordination polymers leads to the variation of the magnetic behavior from a metamagnetic character to a single-chain magnet property.
