Bis{benzyl 3-[(1H-indol-3-yl)methyl- idene]dithiocarbazato-j 2 N 3 ,S}- palladium(II) N,N-dimethylformamide disolvate Hamid Khaledi* and Hapipah Mohd Ali Department of Chemistry, University of Malaya, 50603 Kuala Lumpur, Malaysia Correspondence e-mail: khaledi@siswa.um.edu.my Received 8 December 2010; accepted 10 December 2010 Key indicators: single-crystal X-ray study; T = 296 K; mean (C–C) = 0.004 A ˚; R factor = 0.030; wR factor = 0.074; data-to-parameter ratio = 17.6. In the title compound, [Pd(C 17 H 14 N 3 S 2 ) 2 ]2C 3 H 7 NO, the deprotonated Schiff base ligand acts as an N,S-bidentate chelate, forming a five-membered ring with the metal atom. The Pd II ion, located on an inversion center, is four- coordinated by two of the Schiff base ligands in a square- planar geometry. In the crystal, the indolic NH groups are bonded to the dimethylformamide (DMF) solvent molecules via an N—HO interaction. In addition, C—HS inter- actions are observed.
