Synthesis, Crystal Structure, and Magnetic Properties of a New Dinuclear Iron Complex with Schiff Base Ligand
摘要:
A new dinuclear iron(Ⅲ) complex has been synthesized and structurally characterized by X-ray crystallography: [FeⅢ2(L)(C6H5COO)(SO4)(CH3OH)2]·CH3CN·CH3OH (1, H3L=N,N'-bis(salicylidene)-1,3-diamino-2-propanol). Complex 1 belongs to orthorhombic space group Pna21 with a=11.4400(8), b=22.9705(2), c=12.5712(9)Å, V=3303.5(4)Å3, Z=4, F(000)=1576, Dc=1.531 g·cm-3, Mr=761.36, μ=1.007 mm-1, S=1.014, the final R=0.0505 and wR=0.1018. The crystal packing is stabilized by intermolecular O-H…O hydrogen bonds, forming an extended one-dimensional chain structure. The temperature dependence of magnetic susceptibility measurement shows that antiferromagnetic interaction is propagated between the metal centers. Fit as dinuclear arrangement gave parameters of J=19.7 cm-1, g=1.89 and R2=0.9999.

Abstract:
A new dinuclear iron(Ⅲ) complex has been synthesized and structurally characterized by X-ray crystallography: [FeⅢ2(L)(C6H5COO)(SO4)(CH3OH)2]·CH3CN·CH3OH (1, H3L=N,N'-bis(salicylidene)-1,3-diamino-2-propanol). Complex 1 belongs to orthorhombic space group Pna21 with a=11.4400(8), b=22.9705(2), c=12.5712(9)Å, V=3303.5(4)Å3, Z=4, F(000)=1576, Dc=1.531 g·cm-3, Mr=761.36, μ=1.007 mm-1, S=1.014, the final R=0.0505 and wR=0.1018. The crystal packing is stabilized by intermolecular O-H…O hydrogen bonds, forming an extended one-dimensional chain structure. The temperature dependence of magnetic susceptibility measurement shows that antiferromagnetic interaction is propagated between the metal centers.
