catena-Poly[di-μ₃-benzoato-tetra­-μ₂-benzoato-dipyrrole­tricadmium(II)]

In the title complex, [Cd₃(C₇H₅O₂)₆(C₄H₄N)₂]_n, the benzoate groups adopt μ₃ and μ₂ coordination modes to connect neighbouring cadmium(II) ions into one-dimensional chains. One of the Cd atoms lies on a crystallographic twofold axis.
