From http://www.crystallography.net/cod/1000062.html one can see that Sn sits in the middle, without any displacement, and mimics the classic Rutile-type structure:

I'm not sure what data you used to draw this structure. If you have *.cif file, it might be worth checking occupancies for the atoms you are interested in. Probably there is a 50-50 disordered Sn atom about center of unit cell, and you only observe a single site. I checked original Wikimedia imageWikimedia image, and according to metadata

CIF retrieved from The American Mineralogist Crystal Structure Database

is no longer available. I also failed to discover this source:

X-ray crystallographic data from: R. W. G. Wyckoff (1963) Second edition. Interscience Publishers, New York, New York. Crystal Structures 1, 239-444

Long story shortIdeally, if you have *.cif file, it might be worth checking occupancies for the atoms you are interested in. Probably there is a 50-50 disordered Sn atom about center of unit cell, and you only observe a single site. As long as this is not the case, I would rely on the provided aboveavailable COD data from 1971 instead.
