摘要
For X-H center dot center dot center dot Y hydrogen bonds, a plot of 1/r (X-H) versus 1/r (H center dot center dot center dot Y) is found to be reasonably linear with a negative slope of magnitude less than unity. These observations are explained by using Datta's bond valence sum model (Naskar JP, Hati S Datta D, Acta Crystallogr B 53, 885, 1997). It is revealed that the donor atom plays a more significant role in X-H center dot center dot center dot Y.
