Özet
The reactions of PdCl2(L-L) [L-L = Ph2PCH2PPh2 (dppm), Ph2PCH2CH2PPh2 (dppe) and Ph2PCH2CH2CH2PPh2 (dppp)] with all equivalent amount of Ph2P(S)CH2P(S)Ph-2 (dppmS(2)) gave the cationic complexes [Pd(L-L)(dppmS(2))](2+) which were isolated as perchlorate salts [dppm (1), dppe (2) and dppp (3)]. The complexes 1 and 3 were crystallographically characterized. The coordination geometry around the Pd atoms in these complexes is distorted square planar. Both structures consist of puckered six-membered rights formed by coordination of the disulfide ligands via two sulphur atoms to the metal center. Complex 1 includes one molecule of acetone, [Pd(dppm)(dppmS(2))](ClO4)(2) (.) (CH3)(2)CO (1a). (c) 2005 Elsevier Ltd. All rights reserved.
