Synthesis and Structural Characterization of [(SalpanAl)Li(THF)2]2 and [(SalomphanAl)Li(THF)2]2: A New Class of Aluminum Anion
摘要:
[(SalpanAl)Li(THF)(2)](2) (1) and [(SalomphanAl)Li(THF)(2)](2) (2) are two members of a new class of aluminum anion with metal-ligand stoichiometries of 1:1. Both compounds were spectroscopically and structurally characterized. In 1 (shown) the dihedral angles for the two AlLiO2 planes with respect to the central Al2N2 plane are +50.0 degrees (for Al(1) and -53.2 degrees (for Al(2)). This ''twist'' gives the molecule helical chirality.
