Abstract
A one-dimensional single-chain molecular magnet [{CoII(Δ)CoII(Λ)}(ox)2(phen)2]n with a cross-linked π–π coordination network has been synthesized hydrothermally and investigated for its structural and magnetic properties. Oxalate (ox) ligands bridge the paramagnetic CoII metal ions, whereas phenanthroline (phen) ligands exhibit π–π coordination networks. The compound has been thoroughly investigated using room-temperature X-ray and neutron diffraction, infrared spectroscopy, dc magnetization, and reverse Monte Carlo (RMC) simulation methods. Rietveld refinement of the powder X-ray and neutron diffraction patterns at room temperature confirms the single-phase formation of the compound in the monoclinic structure with a space group P21. Structural analysis reveals that the compound assembles in the form of a one-dimensional zigzag chain-like structure. Chains consist of two asymmetric Δ- and Λ-CoII ions and a π–π coordinating network bridged by ox and phen ligands, respectively. The chain lies in the crysta...
