The space group of the crystal of the title compound is P2/a, with unit cell constants a=12.006, b = 8.398, c= 14.261? ,β= 93.98°. the cell contains two formula units of [phCH2CH(NH3)+CO2C2H5]2? [PtCl4]. The structre was determined from 1759 observed reflections and refined by the block-diagonal least-squares method to R = 0.038. The platinum atoms occupy one set of symmetrical center special positions. The [PtCl4]2- ion is coplanar with Pt-Cl bond, the bond lengths are 2.304(3) and 2.294(3)?, The discreate phenylalanine ethyl ester does not coordinate to the platinum atoms. The [PtCl4]2- ion and [phCH2CH(NH3)+CO2C2H5] ions are connected by ionic fores and hydrogen bonds between the nitrogen and chlorine atoms. Therefore this compound is an adduct of phenylalanine ethylester with anion of chloropladnite.
