摘要：

By using the tripodal tetradentate ligands of tris(2-pyridylmethyl)amine (TPA) or tris(2-benziniidazolylmethyl)amine (NTB), two dinunclear iron(III) complexes [Fe2L2(mu(2)-O)(mu(2)-P-NH2-C6H4COO)](3+) (L=TPA, 1 and L=NTB, 2) were obtained. Both of the two complexes crystallize in monoclinic system with space group P2(1)/c. The cell parameters of 1: a = 1.4529(4) nm, b = 1.6622(5) nm, c = 2.0625(6) nm, beta = 100.327(5)degrees, V=4.900(3) nm(3), Z=4, F(000)=2344, M-r=1142.91, D-c=1.549 g/cm(3), R-1=0.0544, R-2=0.0962. The cell parameters of 2: a=1.3378(4) nm, b=2.1174(7) nm, c=2.4351(7) nm, beta=97.315(6)degrees, V=6.842(4) nm(3), Z=4, F(000)=3116, M-r=1505.08, Dc= 1.444 g/cm(3), R-1=0.0793, R-2= 0.1623. In both cases, the central iron(IR) metal ions are coordinated to the four nitrogen atoms of TPA (or NTB) and two oxygen atoms from two different bridges to form a distorted octahedral geometry.
