Abstract

New silver(I) derivatives containing triorganophosphines and anionic dihydrobis(pyrazol-1-yl)borates have been prepared from AgNO3 and PR3 (R = phenyl, benzyl, cyclohexyl, o-, m- or p-tolyl) or PPh2R′ (R′ = methyl or ethyl) and K[H2B(pz)2] or K[H2B(3,5-Me2pz)2] (Hpz = pyrazole); their solid state and solution properties have been investigated through analytical and spectroscopic measurements (IR, 1H and 31P NMR). The compounds are stable, soluble in chlorinated solvents and non-electrolytes in CH2Cl2 and acetone solutions. The structures of [Ag{H2B(pz)2}(PPh3)2], [Ag{H2B(3,5-Me2pz)2}(PEtPh2)], and [Ag{H2B(3,5-Me2pz)2}(PCy3)] have been determined by X-ray crystallographic studies. In these compounds the dihydrobis(pyrazol-1-yl)borate ligand is bidentate, with the silver(I) centre adopting a tetrahedral (first) or trigonal geometry (last two).
