Abstract

The synthesis and characterization of the diiron(II) complex Fe(2)(μ-OTf)(2)-(PIC(2)DET)(2)(2) (2), where PIC(2)DET is a 2,3-diethynyltriptycene-linked dipicolinic methyl ester ligand, are described. The dication in 2, contains, Fe(2)(μ-OTf)(2)(PIC(2)DET)(2) two symmetry-equivalent iron atoms with octahedral coordination geometries. Each metal ion has a N(2)O(4) atom donor set that includes four atoms from two picolinic ester N,O chelate rings, as well as two oxygen atoms from the bridging trifluoromethanesulfonate groups. The Fe(2)(μ-OTf)(2) core of 2 is stabilized by two PIC(2)DET ligands that bind the two metal ions in a head-to-head fashion, leading to an Fe···Fe distance of 5.173(1)Å. Molar conductivity data for 2 are consistent with Fe(2)(μ-OTf)(2)(PIC(2)DET)(2)](2+) retaining its identity in acetone solutions, where it behaves as a 2:1 electrolyte. (1)H NMR spectroscopic, solution (d(6)-acetone) and solid-state magnetic susceptibility data all indicate that the iron atoms of 2 are high-spin (S = 2). A fit of the magnetic data (2 - 300K) to a spin-only isotropic exchange Hamiltonian H = -2JS(1)·S(2) are consistent with weak antiferromagnetic coupling between the two iron atoms with J ~ -0.99(2) cm(-1) and g = 2.10(1).

摘要

描述了二铁（II）配合物Fe(2)(μ-OTf)(2)-(PIC(2)DET)(2)(2)（2）的合成与表征，其中PIC(2)DET是一种2,3-二乙炔基三联苯连接的二吡啶甲酸甲酯配体。配合物2中的二价阳离子Fe(2)(μ-OTf)(2)(PIC(2)DET)(2)包含两个具有八面体配位几何结构的对称等效铁原子。每个金属离子具有一个N(2)O(4)原子供体集，其中包括来自两个吡啶甲酸酯N,O螯合环的四个原子，以及来自桥连三氟甲磺酸根基团的两个氧原子。配合物2的Fe(2)(μ-OTf)(2)核心由两个以头对头方式结合两个金属离子的PIC(2)DET配体稳定，导致Fe···Fe距离为5.173(1)Å。配合物2的摩尔电导率数据与Fe(2)(μ-OTf)(2)(PIC(2)DET)(2)在丙酮溶液中保持其结构一致，在该溶液中它表现为2:1电解质。(1)H NMR光谱、溶液（d(6)-丙酮）和固态磁化率数据均表明配合物2中的铁原子为高自旋（S = 2）。将磁性数据（2 - 300K）拟合到仅自旋各向同性交换哈密顿量H = -2JS(1)·S(2)，结果与两个铁原子之间的弱反铁磁耦合一致，J ~ -0.99(2) cm(-1)，g = 2.10(1)。
