The novel charge-transfer salt Na+[CAl42−] was produced and characterized in the gas phase. The CAl42− dianion contains a tetracoordinate planar carbon center (see picture), and the Na+ ion is coordinated to an edge of the dianion. The four-center peripheral ligand–ligand bond that is responsible for the planarity of CAl42− is retained in the presence of the countercation; this provides the opportunity to design new bulk ionic materials with CAl42− as a novel structural unit.
