Crystal structure of poly[[μ3-(S)-2-amino-3-hydroxypropanoato]-cis-di-μ-chlorido-caesiumpalladium(II)]

Abstract

The structure of the title compound, [CsPd(C3H6NO3)Cl2]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 Cs2SO4 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.
