Abstract: In the title compound, [Zn(C₈H₄O₄)(C₁₈H₁₀N₄)]_3n·2nC₁₈H₁₀N₄, the three distinct Zn^II atoms each exhibit a distorted cis-ZnN₂O₄ octahedral coordination geometry arising from an N,N-bidentate dipyrido[3,2-a:2,3'-c]phenazine (C₁₈H₁₀N₄; DPPZ) molecule and two O,O-bidentate 1,4-benzenedicarboxylate (C₈H₄O₄; BDC) dianions. The three crystallographically independent [Zn(C₈H₄O₄)(C₁₈H₁₀N₄)]_n polymeric strands propagate in the [001] direction. Two uncoordinated DPPZ molecules complete the asymmetric unit. The structure is stabilized by C-HO, C-HN and - interactions.
