Abstract

In the title compound, [Zn(C8H4O4)(C18H10N4)]3n·2nC18H10N4, the three distinct ZnII 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—H⋯O, C—H⋯N and π–π inter­actions.
