Diamines such as (R, R)-TMCDA (1) form anellated dications with dihalomethanes, which were obtained in the presence of copper(I)halides as salts containing halocuprate anions. Using the chiral diamine (R, R)-TMCDA (1) and its meso-form cis-TMCDA (2) trichloro- and tribromocuprates with trigonal-planar geometry, and with TMEDA (3) a continuous chain of copper(I)iodid were formed. The crystal structures were discussed and compared in terms of the influence of the dication on the structural behavior of the corresponding anion. Overall we revealed an easy access to chiral or achiral dications which are based on the readily available (R, R)-TMCDA (1) and its isomer cis-TMCDA (2).
