title: Poly[bis-(μ(2)-3-carb-oxy-benzoato)bis-(dipyrido[3,2-a;2',3'-c]phenazine)bis-(μ(3)-isophthalato)tricopper(II)].
abstract: In the title compound, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(18)H(10)N(4))(2)](n), one Cu(II) atom, located on an inversion center, is hexa-coordinated and shows a distorted octa-hedral coordination geometry, while the other Cu(II) atom is penta-coordinated and exhibits a distorted square-pyramidal geometry. The Cu(II) atoms are bridged by isophthalate and 3-carb-oxy-benzoate ligands, forming a chain structure along the b axis. Furthermore, the chains are linked by O-H⋯O hydrogen bonds, forming a layer parallel to the ab plane.
