catena-Poly[[bis-(1H-indole-5-carboxyl-ato-κ(2) O,O')zinc(II)]-μ-4,4'-azobi-pyridine-κ(2) N (1):N (1')]

The asymmetric unit of the title coordination polymer [Zn(C(9)H(6)NO(2))(2)(C(10)H(8)N(4))] (n) , consists of one Zn(II) cation, one bidentate 1H-indole-5-carboxyl-ate (I5C) anion and half of a 4,4'-azobi-pyridine (Abpy) neutral ligand. In the coordination polyhedron, the Zn(II) ion adopts a distorted octa-hedral geometry. The coordination polymer is stabilized by a combination of N-H⋯O and C-H⋯π inter-actions, which leads to the formation of wave-like two-dimensional coordination polymeric layers.
