Bonding mode of thiocyanate in palladium(II) phosphite complexes: X-ray structure of trans-dithiocyanatobis(triphenyl phosphite)palladium(II)
Abstract
In contrast to the presence of N-bonded thiocyanate groups in trans-Pd(NCS)2(PPh3)2 the phosphite compound trans-Pd(SCN)2[P(OPh)3]2 contain S-bonded thiocyanates as shown by X-ray crystallographic structure determination: antisymbiosis in the phosphine complexes appears primarily to result from steric inhibition of S-bonding rather than electronic effects.
