Amonia borana

Amonia borana (juga secara sistematis bernama amminetrihidridoboron), juga disebut borazana, adalah senyawa kimia dengan rumus H₃NBH₃. Padatan tidak berwarna atau putih adalah senyawa boron-nitrogen- hidrida molekuler paling sederhana. Ini telah menarik perhatian sebagai sumber bahan bakar hidrogen, tetapi sebaliknya terutama untuk kepentingan akademis.^[1]^[2]

Amonia borana telah diusulkan sebagai media penyimpanan hidrogen, misalnya ketika gas digunakan untuk bahan bakar kendaraan bermotor.

Reaksi diborana dengan amonia terutama menghasilkan garam diamoniat [H₂B(NH₃)₂]⁺(BH₄)⁻.Ammonia borana adalah produk utama ketika adisi borana digunakan sebagai pengganti diborana:^[3]

BH₃(THF) + NH₃ → BH₃NH₃ + THF
