p values and angles of phosphanes to predict their electronic and steric parameters.

Phosphanes play an important role in various applications, serving as a class of organic bases with basicities spanning more than 30 orders of magnitude. Accessing comprehensive basicity data for phosphanes has been challenging due to scattered information across multiple sources and notable gaps in the existing data. In this report, we present basicities (p values) of a diverse set of phosphanes, both newly measured or calculated and collected from the literature.
