Reactivity of [PdC1(bdtp)](BF_4) with monodentate neutral and anionic ligands. Structure of [Pd(bdtp)(PPh_3)](BF_4)_2 (bdtp = 1,5-bis(3,5-dimethyl-1 -pyrazolyl)-3-thiapentane)

摘要

Complex [PdCl(bdtp)](BF_4), in presence of AgBF_4 or NaBF_4, reacts with pyridine (py), triphenylphosphine (PPh_3), cyanide (CN~-), thiocyanate (SCN~-) or azide (N_3~-) ligands, leading to the formation of the following complexes: [Pd(bdtp)(py)](BF_4)_2[1](BF_4)_2, [Pd(bdtp)(PPh_3)](BF_4)-2 [2](BF_4)_2, [Pd(CN)(bdtP)](BF_4) [3](BF_4), [Pd(SCN)(bdtp)](BF_4) [4](BF_4)and [Pd(N_3)(bdtp)](BF_4) [5](BF_4). These complexes were characterised by elemental analyses, mass spectrometry, conductivity measurements, infrared and NMR spectroscopies. The crystal structure of [2](BF_4)_2 was determined by single-crystal X-ray diffraction methods. The metal atom is coordinated by two azine nitrogen atoms, and one sulfur atom of the thioether-pyrazole ligand and one triphenylphosphine in a distorted square-planar geometry.
