Crystal structure of poly[[μ(3)-(S)-2-amino-3-hydroxy­propano­ato]-cis-di-μ-chlorido-caesium­palladium(II)]

The structure of the title compound, [CsPd(C(3)H(6)NO(3))Cl(2)](n), previously shown to have anti­cancer activity in rodent test systems and recently found to have anti­fungal 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 Cs(2)SO(4) structure. X-ray crystal structures of only three di­chlorido­palladium(II)–amino acid complexes have been determined so far and the present paper describes one of those.
