Abstract
Two complexes containing copper(I) chloride and (−)-sparteine (spa), namely [Cu2Cl2spa2] and [Cu4Cl4spa2], have been synthesised from the above-mentioned constituents in the CuCl∶spa ratios 1∶1 and 2∶1, respectively. Characterisation by means of crystal-structure determination shows [Cu2Cl2spa2] to be a discrete dimer and [Cu4Cl4spa2] a discrete complex with an unusual Cu4Cl4 ladder-type core. An unexpected structural similarity between the chlorocopper(I) unit and the methyllithium and phenyllithium units, respectively, became apparent during a closer inspection of the relevant structures.Keywords
