摘要：

Little information is available on the stability of three center hydrogen bonds relative to two center hydrogen bonds. In an XHX three center hydrogen bond, two donors interact with one acceptor; here, we compare an HXH interaction with the component two center hydrogen bonds (H-X and X-H) in a small depsipeptide, 1. The results show that there is negative cooperativity between the two components of the HXH interaction.
