The Tetraphenylester of the μ‐Imido‐Dithiodiphosphoric Acid and its palladium complex — crystal structures

Abstract

Abstract The preparations of [(C 6 H 5 O) 2 PS] 2 NH ( SS ) and its Pd complex [Pd{C 6 H 5 O 2 P(S)NP(S)(OC 6 H 5 ) 2 } 2 ] ( PDSS ) are described. The compounds were characterized by elemental analysis, NMR, and mass spectra and X‐ray structure analysis. The structure of SS contains two independent molecules in an asymmetric unit which are joined into dimers via N …︁ H …︁ S hydrogen bonds. SS is a Br⊘nsted acid And reacts with Pd II to a neutral chelate complex. The structure of PDSS is composed of isolated molecules with Pd atom in the center of symmetry. The Pd atom is coordinated by 4 S atoms in a distorted square‐planar arrangement with average distance PdS 2.345(6) Å and an angle SPdS 98.29(4)°.
