摘要

The coordination polymer [Zn2(C10H8O5)2(H2O)3]n adopts a layer structure in which the two independent Zn^II ions exist in trigonal–bipyramidal coordination geometries. One carboxyl­ate dianion binds to a monoaqua-coordinated metal ion through the aliphatic carboxyl­ate end and to the diaqua-coordinated metal ion through the aromatic carboxyl­ate end; the other dianion binds in the reverse manner. Three of the four carboxyl­ate ends of the two dianions are also engaged in bridging inter­actions; these lead to a layer structure parallel to (100). Adjacent layers are linked by O—Hwater⋯O hydrogen bonds into a three-dimensional network.
