英文摘要	metathesis of linh2bh3 and fecl3 in thf solution was investigated in detail. instead of formation of expected fe amidoborane i.e., 3linh(2)bh(3) + fecl3 -> 3licl + fe(nh2bh3)(3), 1.5 equiv. h-2/linh2bh3 together with licl and a black precipitate was produced as a result of salt metathesis and reduction of fe3+ by bh3. the hydrogen was desorbed in two steps involving a homogeneous interaction of the two starting chemicals to form [fe(h2n=bh2)(3)] precipitate and subsequent solid-state dissociation of [fe(h2n=bh2)(3)] to yield a polymeric product, [fe(hn=bh)(3)](n), respectively. ftir evidenced the persistence of b-h and n-h stretches in the above two solid products and following the dissociation of [fe(h2n=bh2)(3)] to release 1 equiv. h-2/linh(2)bh3 the b-n bond strengthened. mossbauer and xafs both indicated that fe atoms in these solids are in very similar chemical environments, linking to the neighbouring n and b atoms and bearing slightly positive charge. most likely, h2n=bh2 in [fe(h2n=bh2)(3)] binds to fe as a pi-bound ligand. the mechanism of salt metathesis and reduction of fe3+ was confirmed based on simulation work on the homogeneous reaction process.
