Contribution

It provides a formal definition of the pnictogen bond and characterizes its key features and components, establishing a basis for future research.

Findings

Defines the pnictogen bond clearly

Identifies donors and acceptors involved

Characterizes the features of the interaction

Abstract

This article proposes a definition for the term pnictogen bond and lists its donors, acceptors, and characteristic features. These may be invoked to identify this specific subset of the inter- and intra-molecular interactions formed by elements of Group 15 which possess an electrophilic site in a molecular entity.
