“…[14b] The single-crystal X-ray diffraction analysis of 1 revealed the centrosymmetric dimeric structure with two KÀ AlÀ K 3-center-2-electron bonds, supported by the shorter AlÀ K distance of 3.133(2) Å than a sum of covalent radii (4.36 Å for Al and K) [22] (Figure 3). [23] This dimeric structural motif is similar to those of the previously reported diaminoalumanyl anions. The 1 H NMR spectrum of 1 and 3 indicates a C s -symmetrical structure.…”

A non‐solvated alkyl‐substituted Al(I) anion dimer was synthesized by a reduction of haloalumane precursor using a mechanochemical method. The crystallographic and theoretical analysis revealed its structure and electronic properties. Experimental XPS analysis of the Al(I) anions with reference compounds revealed the lower Al 2p binding energy corresponds to the lower oxidation state of Al species. It should be emphasized that the experimentally obtained XPS binding energies were reproduced by delta SCF calculations and were linearly correlated with NPA charges and 2p orbital energies.
