<div><p>The complexes of Al<sub>13</sub>M cluster (M = Li, Na, K, Cu, Ag, Au) and Lewis bases NH<sub>3</sub>, H<sub>2</sub>O, C<sub>6</sub>H<sub>6</sub>, and HLi have been predicted and characterised. The results showed that the cluster Al<sub>13</sub>M forms the alkali-bonding or coinage metal-bonding interaction through M with these Lewis bases. These complexes exhibit some similarities and differences in the structures, properties, and nature with conventional molecules. The formation of these interactions has a negligible or small effect on the structures of Al<sub>13</sub>M. This study combines the cluster Al<sub>13</sub>M with non-covalent interactions, which is of great importance in supramolecular chemistry.</p></div
