An examination of the data sharing practices of authors across 240 organic chemistry papers indicates that less than 20% of manuscripts have any associated primary data, and these are predominantly Cartesian coordinates associated with in silico modelled structures, generally shared in non-machine-readable PDF format. Only 1% of studies shared unprocessed NMR data; despite >93% of research articles reporting NMR data as a main output of their work, and the existence of strongly worded recommendations for NMR data-sharing in the author guidelines of 5/12 journals.
