title: Tetra-aqua-bis[(1-carboxyl-atomethyl-1,3-benzimidazol-3-ium-3-yl)acetato-κO]palladium(II) dihydrate.
abstract: In the title compound, [Pd(C(11)H(9)N(2)O(4))(2)(H(2)O)(4)]·2H(2)O, the palladium(II) cation lies on an inversion centre and is hexa-coordinated by two carboxyl-ate O atoms from two (1-carboxyl-atomethyl-1,3-benzimidazol-3-ium-3-yl)acetate ligands and four water mol-ecules, with a slightly distorted octa-hedral geometry. O-H⋯O hydrogen bonds link the mol-ecules together.
