摘要：
Reaction of [(AIP)Li] with GdBr3 leads to a new mononuclear complex [(AIP)GdBr2(thf)2] 1. In contrast to this with SmI2 the compound [(AIP)3Sm] 2 is build up. Such complexes are also formed with Gd(OR*)3 (R* = OtBu2C6H3) and [(AIP)Li] in a 1:3 ratio, [(AIP)3Gd] 3. The structures of 1 - 3 were characterized by X-ray single crystal structure analysis (1: space group Pna2(1) (No. 33), Z = 4, a = 1 972.7(9) pm, b = 984.7(5) pm, c = 1425.0(8) pm, alpha = beta = gamma = 90-degrees; 2 . 2THF: space group C2/c (No. 15), Z = 8, a = 3644.4(9)pm, b = 1437.5(5)pm, c = 2334.4(7)pm, beta = 121.07(6)-degrees; 3: space group P2(1)/c (No. 14), Z = 4, a = 1 872.9(1) pm, b = 1 064.6(1) pm, c = 2 282.4(2) pm, beta = 103.75(8)-degrees).
