Summary of the results of searches of the CSD (Version 5.23, April 2002) for typical distances (in Å) in hydrogen-bonded systems containing identical functional groups to the paracetamol adducts studied. The distances to H atoms were normalized to typical neutron distances (C—H 1.803, N—H 1.009 and O—H 0.983 Å). Only `organic' structures where the R factor is less than 0.05 with no errors or disorder were included, and ionic or polymeric structures were excluded. The C atoms attached to the amine moieties were specified to be sp3 hybridized. The donor-H-to-acceptor distance was specified to be 1.50–2.20 Å. The asterisk denotes the limit of search. |
