Webb17 jan. 2024 · A Hirshfeld surface is defined by the density weight function of the specific molecule of interest (i.e. the pro-molecule) over the same sum of density of its nearest neighbour (i.e. the pro-crystal), thereby resulting in a 0.5 arbitrary units isosurface, which is similar to that of a van der Waals surface but, unlike the latter, takes into consideration … Hirshfeld surfaces were named after F.L Hirshfeld, whose “stockholder partitioning” scheme for defining atoms in molecules suggested to us an extension to defining a molecule in a crystal. Hirshfeld's original article on that partitioning10has attracted nearly 800 citations to date, more than … Visa mer Aakeröy and Beatty in a recent review2 noted that “predicting and controlling the competition between intermolecular forces such as weak and strong hydrogenbonds, halogen … Visa mer Fig. 2 compares the Hirshfeld surface for the molecule in form I of 2c4n with a fused sphere representation and with the 0.002 au isosurface of the ab initio electron density. As observed earlier for naphthalene and … Visa mer The present example of 2c4n provides us with five different molecular environments for comparison, and the resulting histogram is reproduced in Fig. 8. From this comparison it is … Visa mer Fig. 6 compares fingerprint plots for the four molecules in form II of 2c4n with that for form I. These plots convincingly demonstrate an important feature of the fingerprint plots: they … Visa mer
