Abstract

The structure of the title compound, [CsPd(C₃H₆NO₃)Cl₂] _n , previously shown to have anti-cancer activity in rodent test systems and recently found to have anti-fungal activity, has been determined. The Pd centre is in a square-planar coordination environment with two chlorine atoms in cis positions and the remaining two coordination sites being coordinated by N and O atoms from deprotonated l-serine. Each of the Cs cations shows ninefold coordination with six chlorine and three O atoms resulting in a coordination environment that is similar to the well known Cs₂SO₄ structure. X-ray crystal structures of only three di-chlorido-palladium(II)-amino acid complexes have been determined so far and the present paper describes one of those.

Keywords: l-serine; palladium complex; palladium–amino acid complex; single-crystal X-ray structure.
