Crystal structure of the 1 : 1 adduct formed between bis(cis-1,2-diphenylethylene-1,2-dithiolato)palladium and cyclohexa-1,3-diene

Crystals of the title adduct are triclinic, space group P, with a= 14·347 ± 0·004, b= 13·194 + 0·002, c= 9·461 ± 0·001 Å, α= 72·50 ± 0·02, β= 114·70 ± 0·01, γ= 114·12 ± 0·02°, Z= 2. The structure was refined by least-squares methods to R 0·047 for 2829 observed intensities measured by diffractometer. The analysis shows that a 1,8-addition reaction has occurred between donor and acceptor resulting in the formation of two new carbon–sulphur bonds.
