(a) ConQuest search motifs (CSMs) used to define searches of propargylic donor and acceptor interactions using loosely constrained distances (D1 and D2) and D—H⋯A angles (ANG). (b) Scatterplots of D1 (blue), D2 (green) and D2–D1 (black)(Å) values versus ANG (°) values for interactions in molecules satisfying criteria for ConQuest search motifs CSM1-R1, CSM1-R4, CSM1-R5 and CSM1-R6, including lines of best fit for the D1 and D2 results. (c) Overlay of the four scatterplots of D2–D1 values versus contact angle (ANG) from Fig. 10

(b) (with changed marker shapes and colours), as well as related data points (in red) for relevant contacts in compound 1.
