摘要：

Sn(II) is significantly more tightly bound than Ge(II) in the cavity of the [2.2.2]paracyclophane(L). as shown by the structure analyses of the complex cations [LSn(AlCl4)]+ and [LGeCl]+ 1. In the tin complex the AlCl4- counterion is loosely coordinated via a Cl atom to the metal (Sn-Cl 3.073 angstrom) and thus hardly disturbs the expected trigonal-planar coordination, whereas the strong Ge-Cl bond (Ge-Cl 2.224 angstrom) in 1 leads to a weakening of the Ge-arene interaction and to a perferential tetrahedral environment for the metal.
