Popis:	Bis[3-sulfido-1,3-bis(2-thienyl)prop-2-enone-O,S]palladium(II), [Pd(C 11 H 7 OS 3 ) 2 ], exists as the cis isomer with the O donor atom of one ligand opposite the S donor atom of the other. The mean Pd-O and Pd-S distances are 2.014 (14) and 2.231 (5) A, respectively. Although the mean cis angles around Pd deviate markedly from 90 o , its environment is almost exactly planar. In each independent molecule one of the four thiophene rings is disordered by rotation about its bond to the chelate ring. The result is that while three of the thiophene rings are always endo, the fourth is exo in 50% of the molecules. In neither conformation are there any significant intermolecular Pd...S contacts
