  Weak Ferromagnetism in a Three-Dimensional Manganese(II) Azido Complex, [Mn(4,4‘-bipy)(N₃)₂]_n (bipy = Bipyridine)

  摘要：

  Low-field magnetic studies on [Mn(4,4'-bipyridine)-(N-3)(2)](n) reveal a spontaneous magnetization below ordering temperatures of 42.5 K, due to a transition to a weak ferromagnetic ground state.

  Four compounds of general formula [M(4,4'bipy)(N-3)(2)](n) (M Mn (I), Zn (2), Co (3), Ni (4)) have been synthesized and magnetostructurally characterized by means of X-ray diffraction analysis, IR and ESR spectroscopies, and measurements of the magnetic susceptibility and magnetization. Compound 1 (C10H8N8Mn) crystallizes in the tetragonal P4(3)2(1)2 space Z = 4, with a = 8.229(2), b = 8.229(2), and c = 16.915(2) Angstrom. It exhibits an acentric 3D structure Where - Mn(II) ions are linked through EE-azide groups resulting in a diamondoid network. The 4,4'bipy ligands are coordinated on the axial positions of the octahedral spheres reinforcing, the intermetallic connections. Weak ferromagnetism arising from spin canting is observed for compound 1. Compounds 2, 3, and 4 are proposed to be isomorphous and would consist of a 2D array Where alternating EO + EE/EO + EE/EO + EO azide-chains are linked by 4,4'bipy ligands resulting in pi-pi stacked pyridyl-columns. The azido ligand dispositions in compounds 3 and 4 make possible systems of type -AF-AF-F-, which would give rise to a topological ferromagnetic behavior.
