Coordination complexes that pair a zero-valent transition metal (Ni, Co, Fe) and an aluminum(III) center have been prepared. They add to the few examples of structurally characterized metal alanes and are the first reported metallalumatranes. To understand the M-Al interaction and gauge the effect of varying the late metal, the complexes were characterized by X-ray crystallography, electrochemistry, UV-Vis-NIR and NMR spectroscopies, and theoretical calculations. The M-Al bond strength decreases with varying M in the order Ni > Co > Fe.
已制备出配位复合物，其将零价过渡金属（Ni、Co、Fe）与铝（III）中心配对。它们增加了为数不多的结构特征明确的金属铝烷的实例，并且是首批报道的金属铝烯。为了了解 M-Al 相互作用并衡量改变后期金属的影响，用 X 射线晶体学、电化学、紫外可见近红外和 NMR 光谱以及理论计算对配合物进行了表征。M-Al 键的强度随 M 的变化而降低，顺序为 Ni > Co > Fe。
