Abstract

The title compound, N¹, N²-dimethylethanedihydrazide, C4H10N4O2, was obtained by the methylation of oxalyl dihydrazide protected with phthalimide. The molecule is essentially non-planar with a dihedral angle between the two planar hydrazide fragments of 86.5 (2)°. This geometry contributes to the formation of a multi-contact three-dimensional supramolecular network via C--H...O, N--H...O and N--H...N hydrogen bonds. [ABSTRACT FROM AUTHOR]

Abstract

In the title compound [Fe2(C2O4)(C8H8N4)4](CH3C6H4SO3)2·2.75H2O, the two FeII ions have a highly distorted octa­hedral FeN4O2 environment formed by two bidentate triazole-based chelating ligands and a bis-bidentate oxalate bridging anion that connects the metal ions. Stabilization within the crystal structure is provided via a system of O--H⋯O and N--H⋯O hydrogen bonding, which determines the formation of a two-dimensional architecture along the a-axis direction.
