The Ionic Radii data was obtained from http://abulafia.mt.ic.ac.uk/shannon/ptable.php. We want to make a json file from this data so we can easily obtain the ionic radius for an element with a given charge and coordination. This data might be useful for many things, I use it to obtain radii for input into Zeo++ (http://www.maciejharanczyk.info/Zeopp/).
The compiled json file can be found at ./shannon-radii.json.
The full table and the python script to compile the json file is at ./compile.org.
Usage is shown below.
import json
with open("shannon-radii.json") as f:
out = f.read()
d = json.loads(out)
# Enter Element, Charge, Coordination and one of - r_crystal, r_ionic, spin, remark
print d['Cd']['2']['VII']['r_ionic']
