catena-Poly[di-μ_1,1-azido-(1,10-phenanthroline)cadmium(II)]

Abstract

The asymmetric unit of the title CdII compound, [Cd(N3)2(C12H8N2)]n, contains a CdII atom, located on a twofold axis passing through the middle of the phenanthroline mol­ecule, one azide ion and half of a 1,10-phenanthroline mol­ecule. The CdII atom exhibits a distorted octa­hedral coordin­ation including one chelating 1,10-phenanthroline ligand and four azide ligands. The crystal structure features chains along the c direction in which azide groups doubly bridge two adjacent CdII atoms in an end-on (EO) mode. Inter­chain π–π stacking inter­actions, with centroid–centroid separations of 3.408 (2) Å between the central aromatic rings of 1,10-phenanthroline mol­ecules, lead to a supra­molecular sheet parallel to the bc plane.
