atoms of the crown in a half-sandwich structure while compound (2) has the ionic formulation 2[BiCl2·18-crown-6]+[Bi2Cl8]2–, in which the bismuth cation is eight-co-ordinate involving all six oxygen atoms of the crown and two chlorine atoms in bicapped trigonal prismatic geometry. ...
Geometry-enhanced molecular representation learning for property prediction ArticleOpen access07 February 2022 Introduction The identification of molecules with desired properties presents one of the most significant challenges in the drug discovery field, given the considerable time and resources required for ...
Geometry optimisation The constrained conformer generation described above aims to enumerate all accessible, physically-reasonable conformers of the added R-group (and any other flexible regions) in vacuum. However, most of these conformations will be incompatible with the protein binding site. Hence, ...
