[Ifeffit] EXAFS fitting method

As I understand, the EXAFS fitting procedure using Artemis, for
generating a theoretical model requires the crystal structure parameter like
space group, cell parameters and *specially* *atom coordinates* etc. For
this we have to perform XRD measurements of single crystals of the samples.
I have some questions
(1) In case we dont have the XRD data of a sample then how can the EXAFS
analysis be done of that sample?
(2) If we have already performed the XRD on the sample then by doing
EXAFS what additional information are we getting ?
(3) If the answer to the first question is that - *use the crystal structure
of a *
* similar sample,* then what are the conditions under which we can use
known crystal structure of one sample for other samples ?
Thanks in advance
