Abstract Indium(III) chloride reacts with 12-c-4 to give the 1:1 adduct [InCl3·12-c-4]. This complex is a convenient In precursor to liquid clathrates. [InCl3·12-c-4] reacts with LiCl to form [Li·12-c-4] [InCl4]. When the reaction is carried out in the presence of an aromatic solvent such as toluene, a liquid inclusion complex forms readily. It has been determined that the C6H5CH3:[Li·12-c-4] [InCl4] ratio is 2. Alkylation of the 15-c-5 adduct of InCl3 with methyllithium yields [Li·15-c-5] [In(CH3)3Cl]. The salt fails to form inclusion complexes with aromatic molecules. This compound has been characterized using single crystal X-ray diffraction. The molecule belongs to the monoclinic space groupP21/n, witha=7.515(2),b=18.952(6), andc=13.938(7) Å, β=95.12(3)° andD calc=1.43 g cm−3 for Z=4. Least squares refinement based upon 2348 observed reflections led to a finalR=0.039.
