A new ZnIIcoordination polymer with intermolecular π–π interactions:catena-poly[[aqua(dipyrido[3,2-a:2′,3′-c]phenazine)zinc(II)]-μ-benzene-1,4-dicarboxylato

Abstract

In the title compound, [Zn(1,4-BDC)(L)]n, where 1,4-BDC is the benzene-1,4-dicarboxyl­ate dianion, C7H3O4N2−, and L is dipyrido[3,2-a:2′,3′-c]-phenazine, C18H10N4, each ZnII atom is five-coordinated by two N atoms (from one dipyrido[3,2-a:2′,3′-c]phenazine ligand) and three O atoms (from two monodentate benzene-1,4-dicarboxyl­ate ligands and one water mol­ecule). The ZnII atoms are bridged by benzene-1,4-dicarboxyl­ate ligands, forming a one-dimensional chain structure. Neighboring one-dimensional chains inter­act through π–π contacts, leading to a two-dimensional supra­molecular structure, and O—H⋯O hydrogen bonds complete the structure.
