In the hydrated title complex, [Fe(dpa)2(N3)2]·H2O (dpa is 2,2'-di-pyridyl-amine, C10H9N3), the FeII ion is coordinated in a distorted octa-hedral manner by two neutral, chelating dpa ligands and two anionic, monodentate azide (N3-) ions in a cis-configuration. Distortion results from different Fe-N bond lengths [2.1397 (13)-2.2254 (12) Å] and (N-Fe-N) cis [80.12 (4)-96.72 (5)°] and (N-Fe-N) trans [166.73 (4)-176.62 (5)°] bond angles. Hydrogen bonds exist between two symmetry-related water mol-ecules as hydrogen donors to the γ-N atoms of azido ligands of two adjacent iron complexes and as acceptors from the amide group of the dpa ligands of two additional iron complexes. The hydrogen-bonding pattern results in eight-membered ⋯H-O-H⋯N⋯ rings and a band-like arrangement of the mol-ecules involved. Additional, weaker hydrogen bonds between the α-N atom of the second azido ligand as acceptors and the amide groups of the second dpa ligands as donors cross-link neighboring bands to layers extending parallel to (001).
