Abstract
In the title compound, [Pd(C5H8NO4)2], the Pd(II) atom is coordinated by two O atoms and two N atoms of two N,O-chelating hydrogen l-glutatmate ligands in a square–planar geometry with the N and O atoms in a mutually trans arrangement. The complex units are embedded in a network of N—H⋯O and O—H⋯O hydrogen-bonding interactions that stabilize the three-dimensional crystal structure. The strongest hydrogen bonds are formed between the γ-COOH untis of adjacent glutamate ligands, leading to dimers of the type R 2 2(8) with O⋯O separations of 2.640 (6) Å.
