Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Data availability statement. Crystallographic data for 2⊃16, (5)2⊃17, (5)2⊃21, (5)4⊃22, (5)6⊃23, and (3.(6)2)⊃27 have been deposited with the Cambridge Crystallographic Data Centre under reference numbers CCDC-1482309, 1482270, 1482295, 1482290, 1482301, and 1482282 respectively. These data can be obtained free of charge from the Cambridge Crystallographic Data Centre (http://www.ccdc.cam.ac.uk/data_request/cif). Other data that support the findings of this study (spectroscopic or mass spectrometric data) are available from the corresponding author upon reasonable request.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
