title: N,N'-Bis(2-pyridylmethyl)ferrocene-1,1'-diyldicarboxamide and N,N'-bis(3-pyridylmethyl)ferrocene-1,1'-diyldicarboxamide.
abstract: The molecules of N,N'-bis(2-pyridylmethyl)ferrocene-1,1'-diyldicarboxamide, [Fe(C12H11N2O)2], contain intramolecular N-H...N hydrogen bonds and are linked into sheets by three independent C-H...O hydrogen bonds. The molecules of the isomeric compound N,N'-bis(3-pyridylmethyl)ferrocene-1,1'-diyldicarboxamide lie across inversion centres, and the molecules are linked into sheets by a combination of N-H...N hydrogen bonds and pi-pi stacking interactions between pyridyl groups.
