A cadmium coordination polymer containing helical chains:catena-poly[[(dipyrido[3,2-a:2′,3′-c]phenazine)cadmium]-μ-benzene-1,3-dicarboxylato]

Abstract

The title compound, [Cd(C8H4O4)(C18H10N4)]n, was synthesized under mild hydro­thermal conditions. The Cd center is coordinated by four O atoms from three different benzene‐1,3‐dicarboxyl­ate ligands and two N atoms from the dipyrido[3,2‐a:2′,3′‐c]phenazine ligand in a distorted octa­hedral geometry. The polymeric chain extends along the c axis, forming a one‐dimensional helical structure.

“…1,10-Phenanthroline and its derivatives are important ligands with numerous uses in the construction of metal-organic complexes. As part of our ongoing studies in this area (Li et al, 2006), we employed dipyrido[3,2-a:2 0 3 0 -c]phenazine (dppz) as a chelating ligand, generating a new Zn II compound [ZnCl 2 (dppz) 2 ], (I), which is reported here.…”
