Abstract

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.

20 We initially optimized geometries and calculated frequencies of Na⁺[CAl₄²⁻] and (Na⁺)₂[CAl₄²⁻] by using analytical gradients with polarized split-valence basis sets (6-311+G*) and a hybrid method known in the literature as B3LYP. Then we refined geometries and calculated frequencies at the second-order Møller-Plesset perturbation theory (MP2) level. The energies of the lowest energy structures were refined by using the coupled-cluster (CCSD(T)) method and the more extended 6-311+G(2df) basis sets. The first ADE of Na⁺[CAl₄²⁻] were calculated by using the CCSD(T)/6-311+G(2df) method. The VDEs were calculated by the outer valence green function method (OVGF) with 6-311+G(2df) basis sets. All core electrons were kept frozen in treating the electron correlation at the MP2, CCSD(T), and OVGF levels of theory.
