In chemical systems, the arsenic-centered pnictogen bond, or simply the arsenic bond, occurs when there is evidence of a net attractive interaction between the electrophilic region associated with a covalently or coordinately bound arsenic atom in a molecular entity and a nucleophile in another or the same molecular entity. It is the third member of the family of pnictogen bonds formed by the third atom of the pnictogen family, Group 15 of the periodic table, and is an inter- or intramolecular noncovalent interaction. In this overview, we present several illustrative crystal structures deposited into the Cambridge Structure Database (CSD) and the Inorganic Chemistry Structural Database (ICSD) during the last and current centuries to demonstrate that the arsenic atom in molecular entities has a significant ability to act as an electrophilic agent to make an attractive engagement with nucleophiles when in close vicinity, thereby forming σ-hole or π-hole interactions, and hence driving (in part, at least) the overall stability of the system’s crystalline phase. This overview does not include results from theoretical simulations reported by others as none of them address the signatory details of As-centered pnictogen bonds. Rather, we aimed at highlighting the interaction modes of arsenic-centered σ- and π-holes in the rationale design of crystal lattices to demonstrate that such interactions are abundant in crystalline materials, but care has to be taken to identify them as is usually done with the much more widely known noncovalent interactions in chemical systems, halogen bonding and hydrogen bonding. We also demonstrate that As-centered pnictogen bonds are usually accompanied by other primary and secondary interactions, which reinforce their occurrence and strength in most of the crystal structures illustrated. A statistical analysis of structures deposited into the CSD was performed for each interaction type As···D (D = N, O, S, Se, Te, F, Cl, Br, I, arene’s π system), thus providing insight into the typical nature of As···D interaction distances and ∠R–As···D bond angles of these interactions in crystals, where R is the remainder of the molecular entity.

The zinc complexes of diphenylarsinate [(Ph 2 AsO 2 )ZnCl] (1), [(Ph 2 AsO 2 )Zn(Ph 2 As(O)OH)Cl] (2) and [(Ph 2 AsO 2 ) 2 Zn] (3) were prepared through the reaction of ZnCl 2 with dihydroxodiphenylarsonium chloride [Ph 2 As(OH) 2 ]Cl. Single-crystal X-ray diffraction analyses indicate that all three compounds form 1D polymer chain arrangements. Specifically, the [Ph 2 AsO 2 ] À ligand coordinates with three Zn centres giving a syn,syn,anti μ 3 -η 1 : η 2 mode in compound 1. A more diverse binding mode arised in compound 2: [Ph 2 AsO 2 ] À shows a syn,anti μ 2 -η 1 : η 1 bridging mode; while free ligand Ph 2 As(O)OH is bound to Zn through the oxygen atom of the As=O unit (monodentate). In addition, the hydrogen atom of Ph 2 As(O)OH forms a moderate hydrogen bond with the oxygen atom of [Ph 2 AsO 2 ] À . Even though all [Ph 2 AsO 2 ] À ligands also coordinate in a bridging mode in compound 3, a chain-like arrangement with alternate single (anti,anti μ 2 -η 1 : η 1 ) and triple (syn,syn μ 2 -η 1 : η 1 ) bridging diphenylarsinate groups between tetrahedrally coordinated Zn atoms was identified.
