The search for new molecular materials with interesting magnetic properties using the pseudohalide azide ion and quinolin-8-amine (aqin, C9H8N2) as a chelating ligand, led to the synthesis and structure determination of the title complex, [Fe(N3)2(C9H8N2)2]. The complex shows an octahedral geometry, with the FeII atom surrounded by six N atoms; the two N3- anions coordinate in a cis configuration, while the remaining N atoms originate from the two quinolin-8- amine ligands with the quinoline N atoms lying on opposite sides of the Fe atom. The crystal packing is dominated by layers of hydrophilic and aromatic regions parallel to the ac plane, stabilized by a two-dimensional hydrogen-bonded network and pi–pi stacking.
