Abstract: The title compound, {[Pd₂(C₁₇H₆O₉)(C₁₂H₈N₂)₄]·2H₂O}_n, was prepared by hydrothermal synthesis and is isostructural with its Cd²⁺-containing analogue. A twofold rotation axis passes through the carbonyl group of the benzophenone unit. In the asymmetric unit, the Pd atom exhibts a distorted octahedral geometry, consisting of two carboxylate O atoms from two 4,4'-carbonylbis(benzene-3,4-dicarboxylate) anions and four N atoms from two 1,10-phenanthroline ligands. The Pd-N and Pd-O bond lengths are in the ranges 2.391 (3)-2.520 (3) and 2.270 (2)-2.523 (3) Å, respectively. Two neighboring Pd atoms are bridged by 4,4'-carbonylbis(benzene-3,4-dicarboxylate) anions, forming a dinuclear complex, which is further bridged by 4,4'-carbonylbis(benzene-3,4-dicarboxylate) anions to form an infinite chain. Hydrogen bonds link the chains into a three-dimensional structure.
