title: catena-Poly[[[tetra-aqua-iron(II)]-μ-5,5'-diazenediylditetra-zolido] dihydrate].
abstract: In the title compound, {[Fe(C(2)N(10))(H(2)O)(4)]·2H(2)O}(n), the coordin-ation geometry around the Fe(II) atom, which lies on a center of inversion, is distorted octa-hedral, with bonds to four O atoms and two N atoms. The azotetra-zolate ligand displays a bridging coordination mode, forming an infinite zigzag chain. Inter-molecular O-H⋯O and O-H⋯N hydrogen bonding and offset face-to-face π-π stacking inter-actions [centroid-centroid distance = 3.4738 (13) Å] lead to a three-dimensional network.
