The title linear trinuclear complexes,[Fe_3L_2(CH_3COO)_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.[Fe_3L_2(CH_3COO)_2](1)was obtained using and space group of P2_1/c,and lattice parameters of a=O.945 0(8)am,b=1.037 0(8)nm,c=1.830 5(14)nm,β=94.357(16)°.The[Fe_3L_2(CH_3COO)_2](2)wa.s obtained using1,4-diaminobutane instead of 1,3-diaminopropane while keeping the other conditions the sanle as that for synthesis of[Fe_3L_2(CH_3COO)_2](1).The[Fe_3L_2(CH_3COO)_2](2)was in monoclinic crystal system and space group of P2_1/c,and lattice parameters of a=0.9190(5)nm,b=1.675 6(9)am,c=1.2700(7)nm,β=95.126(11)°.
