Figure 1
Large variations of donor⋯acceptor distances in hydrogen bonds. Hydrogen-bond energies E as a function of D⋯A distances; negative or positive charge-assisted hydrogen bonds marked as (−) or (+); ordinary hydrogen-bond marked as (•); colored horizontal lines on the bottom show the ranges of variation of the D⋯A distances for each type of bond from dD·A (vdW) to the shortest value dD. The dashed curve connecting the (•) points represents the particularly weak interactions with organic halogen acceptors. Reprinted with permission from Gilli et al. (2009  ).
