资源简介:
The new very-intense vertical-axis Laue diffractometer (VIVALDI) at the Institut Laue-Langevin has been used to probe the single-crystal structure of [(t-Bu2AlMe2)2Li]-[{Ph(2-C5H4N)N}6HLi8]+, with data proving that the molecular main-group-metal cluster cation component incorporates interstitial hydride. Variations in nitrogen coordination mode and distortion of the metal core are in accord with octahedral hydride coordination (H−Li = 1.92(2), 2.04(2), 2.07(2) Å), two metal centers being nonbonding with respect to hydride (H···Li = 2.86(2) Å).
