catena-Poly[[bis(1H-indole-5-carboxylato-κ2O,O′)zinc(II)]-μ-4,4′-azobipyridine-κ2N1:N1′]

Abstract

The asymmetric unit of the title coordination polymer [Zn(C9H6NO2)2(C10H8N4)]n, consists of one ZnII cation, one bidentate 1H-indole-5-carboxylate (I5C) anion and half of a 4,4′-azobipyridine (Abpy) neutral ligand. In the coordination polyhedron, the ZnII ion adopts a distorted octahedral geometry. The coordination polymer is stabilized by a combination of N—H...O and C—H...π interactions, which leads to the formation of wave-like two-dimensional coordination polymeric layers.
