Structures of cyclodextrin complexed with small ligands
I looked for relevant publications at Web of Science using 'structur* AND cyclodextrin' in the Title field. For the period 2011-2012 there were 56 hits including:


  Racz et al (2012) Structure of the inclusion complex of beta-cyclodextrin with lipoic acid from laboratory powder diffraction data. Acta Crystallographica Section B 68: 164-170
  
  Ali et al (2012) Structure determination of fexofenadine-a-cyclodextrin complex by quantitative 2D ROESY analysis and molecular mechanics studies. Magnetic Resonance in Chemistry 50:299-304
  
  Lula et al (2012) Interaction between bradykinin potentiating nonapeptide (BPP9a) and beta-cyclodextrin: A structural and thermodynamic study. Materials Science &amp; Engineering C 32: 244-253


I looked at some of the papers but I didn't find any specific case where a structure has been deposited in a database. There were, however, several mentions of the Cambridge Crystallographic Data Centre  as a source of small molecule structures.
