| Abstract |
The design of novel supramolecular synthons for functional groups relevant to drugs is an essential prerequisite for applying crystal engineering in the development of novel pharmaceutical cocrystals. It has been convincingly shown over the past decade that molecular level control and modulation can influence the physicochemical properties of drug cocrystals. Whereas considerable advances have been reported on the design of cocrystals for carboxylic acids and carboxamide functional groups, the sulfonamide group, which is a cornerstone of sulfa drugs, is relatively unexplored for reproducible heterosynthon-directed crystal engineering. The occurrence of synthons and isostructurality in sulfonamide-lactam cocrystals (SO2NH2⋯CONH hydrogen bonding) is analyzed to define a strategy for amide-type GRAS (generally recognized as safe) coformers with sulfonamides. Three types of supramolecular synthons are identified for the N-H donor of sulfonamide hydrogen bonding to the C=O acceptor of amide. Synthon 1: catemer synthon C 2 (1)(4) chain motif, synthon 2: dimer-cyclic ring synthon R 2 (2)(8)R 4 (2)(8) motifs, and synthon 3: dimer-catemer synthon of R 2 (2)(8)C 1 (1)(4)D notation. These heterosynthons of the cocrystals observed in this study are compared with the N-H⋯O dimer R 2 (2)(8) ring and C(4) chain motifs of the individual sulfonamide structures. The X-ray crystal structures of sulfonamide-lactam cocrystals exhibit interesting isostructurality trends with the same synthon being present. One-dimensional, two-dimensional and three-dimensional isostructurality in crystal structures is associated with isosynthons and due to their recurrence, novel heterosynthons for sulfonamide cocrystals are added to the crystal engineer's toolkit. With the predominance of sulfa drugs in medicine, these new synthons provide rational strategies for the design of binary and potentially ternary cocrystals of sulfonamides. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 August 2020.
All research outputs
#14,160,518
of 22,803,211 outputs
Outputs from IUCrJ
#559
of 854 outputs
Outputs of similar age
#137,845
of 264,364 outputs
Outputs of similar age from IUCrJ
#10
of 15 outputs
Altmetric has tracked 22,803,211 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 854 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.0. This one is in the 33rd percentile – i.e., 33% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 264,364 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 47th percentile – i.e., 47% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
