A TETRANUCLEAR COMPLEX OF PALLADIUM(II) WITH CYSTEINE

The title compound, ato-N,S:S)tetrakis]-[chloropalladium(II)]-dimethyl sulfoxide-diethyl ether (1/3/1), [Pd4Cl4(mu-C3H6NO2S)(4)]. 3(CH3)(2)S O. (CH3CH2)(2)O, contains four nearly square-planar units in each of w hich the palladium(II) ion is bound to two doubly-bridging thiolate an ions from two N,S-bidentate cysteinate ligands, the amino group from o ne of these ligands, and a chloride anion. The two Pd ... Pd distances in the pairs that are not bridged by the thiolate ligands are 3.203(1 ) and 3.239(1)Angstrom. If there is any covalent bonding across these distances, it must be very weak.
