A new family of silver(i) complexes stabilised by the phosphanylborane (C6H5)2PBH2·N(CH3)3

Abstract

The reactions of the phosphanylborane Ph₂PBH₂·NMe₃ (L) with Ag[FAl{OC₆F₁₀(C₆F₅)}₃] (Ag[FAl]) and AgBF₄ are studied. The first reaction allowed for the synthesis of the coordination compounds [Ag(Ph₂P-BH₂·NMe₃)(CH₃CN)][FAl] (1), [Ag(Ph₂P-BH₂·NMe₃)₂][FAl] (2) and [Ag(Ph₂P-BH₂·NMe₃)₃][FAl] (3), while the second reaction afforded the one-dimensional coordination polymer [Ag(Ph₂P-BH₂·NMe₃)]_n[BF₄]_n (4). Compounds 1–4 are the first reported Ag(I) complexes stabilised by phosphanylboranes.
