A new dinuclear iron(Ⅲ) complex has been synthesized and structurally characterized by X-ray crystallography: [Fe^Ⅲ₂(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, D_c=1.531 g·cm^-3, M_r=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.
