The reactivity of the terminal phosphido complex [(N3N)W equivalent to P] (1) (N3N = tren = N(CH2CH2NSiMe3)(3)) towards the coinage metal salts [Au(tht)Cl] (tht = tetrahydrothiophene) as well as [Au(MeCN)(4)](+)[pftb] containing the weakly coordinating anion [Al(OC{CF3)(3)}(4)] (pftb) was investigated. The complexes [{(N3N)W equivalent to P-AuCl] (2) as well as [{(N3N)W equivalent to P}(2)Au](+)[pftb] (3) were formed in good yields and were characterized by spectroscopic methods, mass spectrometry and single crystal X-ray diffraction. In the solid state, all complexes present a linear coordination around the gold center but the W-P-Au-P-W unit in 3 is bent. DFT calculations shed light on the electronic structure of these complexes and show that the bending of the W-P-Au-P-W unit is due to the dispersion effects between the Me3Si groups of the tren ligand. The triple bond nature of the W-P bond is preserved in 2 and 3. (C) 2017 Elsevier B.V. All rights reserved.
