A neat way to get generic coordinates of organic molecules like this is using Jmol:
1) go to http://chemapps.stolaf.edu/jmol/docs/examples-12/new.htm?USESIGNED This requires Sun/Oracle Java plugin activated in the browser and asks for permission to trust the signed applet. Alternatively one could use the Jmol Application instead. 2) type the following two commands into the "cmd" textbox (or the Jmol console) load "$Thiophene" ; write coords "?" ; The first one will load the structure and the second one will open a Save-File dialog to ask for the filename to save it on your hard disk. Quoting Bob Hanson (currently the lead Jmol developer): "If you can name it [and if it is organic] [...] you can probably get it."
