Abstract
The title compound was prepared by a template synthesis from 2,6-diacetylpyridine, dioxamohydrazide and Fe(ClO 4 ) 3 ·6H 2 O (mol ratio 1 : 2 : 1) in MeOH/H 2 O (3 : 1) solution and its structure determined by single-crystal X-ray diffraction; triclinic, space group $ P\bar 1 $ , a = 7.5186(7), b = 10.9730(9), c = 14.6110(10) Å, α = 95.866(1), β = 100.252(1), γ = 92.895(1), z = 2. The polydentate ligand is coordinated as a dianionic pentadentate while water molecules occupy apical positions in the structure. This is the first example of a monomeric, pentagonal bipyramidal structure of an Fe(III) complex with a dianionic bis(acylhydrazone) derivative of 2,6-diacetylpyridine. [ABSTRACT FROM AUTHOR]
