a

Overall best fit for each sample from progressive addition of scattering environments is in bold. A denotes the coordinating atom.

b

As–ligand bond length in Å. Multiple data sets have a standard deviation of 0.01 Å.

c

As–ligand coordination number. Multiple data sets have a standard deviation of 0.5.

d

Debye–Waller factor in ×103 Å2. Multiple data sets have a standard deviation of 1.23 Å2.

e

Number of degrees of freedom weighted goodness-of-fit parameter. Multiple data sets have a standard deviation of 0.23.
