Reactivity of [PdCl(bdtp)](BF₄) with monodentate neutral and anionic ligands. Structure of [Pd(bdtp)(PPh₃)](BF₄)₂ (bdtp = 1,5-bis(3,5-dimethyl-1-pyrazolyl)-3-thiapentane)

Complex [PdCl(bdtp)](BF4), in presence of AgBF4 or NaBF4, reacts with pyridine (py), triphenylphosphine (PPh3), cyanide (CN-), thiocyanate (SCN-) or azide (N3-) ligands, leading to the formation of the following complexes: [Pd(bdtp)(py)](BF4)2 [1](BF4)2, [Pd(bdtp)(PPh3)](BF4)2 [2](BF4)2, [Pd(CN)(bdtp)](BF4) [3](BF4), [Pd(SCN)(bdtp)](BF4) [4](BF4) and [Pd(N3)(bdtp)](BF4) [5](BF4). These complexes were characterised by elemental analyses, mass spectrometry, conductivity measurements, infrared and NMR spectroscopies. The crystal structure of [2](BF4)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. © 2009 Elsevier B.V.
