Design, Synthesis, and Structural Characterization of Molecular and Supramolecular Heterobimetallic Metallamacrocycles Based on the 1,1‘-Bis(4-pyridyl)ferrocene (Fe(η5-C5H4-1-C5H4N)2) Ligand
摘要:
The bidentate ferrocenyl sandwich [Fe(eta(5)-C5H4-1-C5H4N)(2)] (1) has been used as a coordination ligand in reactions with AgNO3, Cd(NO3)(2), Cu(CH3COO)(2), Zn(CH3COO)(2), and ZnCl2 to obtain the heterobimetallic metallamacrocyclic derivatives [Fe(eta(5)-C5H4-1-C5H4N)(2)](2)Ag-2(NO3)(2).1.5H(2)O, [Fe(eta(5)-C5H4-1-C5H4N)(2)](2) Cu-2(CH3COO)(4).3H(2)O, [Fe(eta(5)-C5H4-1-C5H4N)(2)](2)Cd-2(NO3)(4).CH3OH.0.5C(6)H(6), [Fe(eta(5)-C5H4-1-C5H4N)(2)](2)Zn-2(CH3COO)(4), and [Fe(eta(5)-C5H4-1-C5H4N)(2)](2)Zn2Cl4 (abbreviated in the following as (1Ag(I))(2)(2+), (1Cd(II))(2)(4+), (1Cu(II))(2)(4+), (1Zn(acetate)(II))(2)(4+), and (1Zn(chloride)(II))(2)(4+)). The reaction with the ferrocenedicarboxylic acid complex [Fe(eta(5)-C5H4COOH)(2)] has led to the supramolecular adduct [Fe(eta(5)-C5H4-1-C5H4N)(2)] [Fe(eta(5)-C5H4COOH)(2)] (1[Fe(eta(5)-C5H4COOH)(2)]). All compounds have been structurally characterized by single-crystal X-ray diffraction.
