Remarkably volatile magnesium complexes have been prepared with the modified borohydride ligand N,N-dimethylaminodiboranate, H(3)BNMe(2)BH(3)(-). The homoleptic complex Mg(H(3)BNMe(2)BH(3))(2), its monoadducts with tetrahydrofuran and 1,2-dimethoxyethane, and the mixed ligand complex (C(5)Me(5))Mg(H(3)BNMe(2)BH(3))(thf) have been prepared. The homoleptic complex Mg(H(3)BNMe(2)BH(3))(2) has a vapor pressure of 800 mTorr at 25 degrees C, which makes it the most volatile magnesium complex known. Crystal structures and NMR data are reported for all complexes. The compounds are potentially useful as chemical vapor deposition precursors to MgB(2) and MgO, and as hydrogen storage materials.
已经用改性硼氢化物配体 N,N-二甲基氨基二硼酸盐 H(3)BNMe(2)BH(3)(-) 制备了具有显著挥发性的镁配合物。制备了具有挥发性的镁配合物：同核配合物 Mg(H(3)BNMe(2)BH(3))(2)、其与四氢呋喃和 1,2-二甲氧基乙烷的单加合物以及混合配体配合物(C(5)Me(5))Mg(H(3)BNMe(2)BH(3))(thf)。同核配合物 Mg(H(3)BNMe(2)BH(3))(2)在 25°C 时的蒸气压为 800 毫托，使其成为已知的挥发性最高的镁配合物。报道了所有配合物的晶体结构和 NMR 数据。这些化合物有望用作 MgB(2)和 MgO 的化学气相沉积前体以及储氢材料。
