两个线型三核铁(Ⅱ)配合物[Fe3L2(CH3COO)2]的合成和晶体结构

The title linear trinuclear complexes, [Fe₃L₂(CH₃COO)₂](L=bis-(salicylidene)-1,3-diaminopropane (salpd) (1) and L=bis-(salicylidene)-1,4-diaminobutane (salbd) (2) were synthesized simply using solvothermal method in methanol and were characterized by X-ray single crystal diffraction. [Fe₃L₂(CH₃COO)₂](1) was obtained using salicylaldehyde, 1,3-diaminopropane and Fe(CH₃COO)₂·4H₂O via the above method with monoclinic crystal system and space group of P2₁/c, and lattice parameters of a=0.945 0(8) nm, b=1.037 0(8) nm, c=1.830 5(14) nm, β=94.357(16)°. The [Fe₃L₂(CH₃COO)₂](2) was obtained using1,4-diaminobutane instead of 1,3-diaminopropane while keeping the other conditions the same as that for synthesis of [Fe₃L₂(CH₃COO)₂] (1). The [Fe₃L₂(CH₃COO)₂](2) was in monoclinic crystal system and space group of P2₁/c, and lattice parameters of a=0.919 0(5) nm, b=1.675 6(9) nm, c=1.270 0(7) nm, β=95.126(11)°. CCDC: 754930, 1; 754931, 2.
