The title compound, [PdCl2(C21H12F9P)2]·CH2Cl2, crystallizes with two independent complex molecules (each having the PdII atom situated on an inversion centre) and a dichloro­methane molecule in the asymmetric unit. The independent PdII atoms are in perfectly linear orientations of the ligands in mutually trans positions, but distortions of the Cl—Pd—P angles ranging from 86.151 (19) to 93.849 (19)° are evident. The effective cone angles for the tris­[4-(trifluoro­meth­yl)phen­yl]phosphane ligand were calculated to be 159 and 161°. In the crystal, weak C—H⋯Cl/F inter­actions create a three-dimensional supramolecular network.

25.  Crystal structure of 6-(4-chloro­phen­yl)-6a-nitro-6,6a,6b,7,9,11a-hexa­hydro­spiro[chromeno[3′,4′:3,4]pyrrolo­[1,2-c]thia­zole-11,11′-indeno­[1,2-b]quinoxaline] chloro­form monosolvate 
In the title compound, C33H23ClN4O3S·CHCl3, the thia­zole ring adopts an envelope conformation with the N atom as the flap, and the pyrrolidine ring adopts a half-chair conformation. The thia­zole ring mean plane makes a dihedral angle of 59.31 (1)° with the pyrrolidine ring mean plane, 71.67 (1)° with the chromene ring and 82.59 (1)° with the chloro­benzene ring. An intra­molecular C—H⋯N hydrogen bond occurs. In the crystal, a second C—H⋯N hydrogen bond links the main and solvent mol­ecules. The solvent chloroform molecule is disordered about two positions with an occupancy ratio of 0.508 (14):0.492 (14).
