Chirality space group
WebJan 20, 2024 · Unlike space groups with enantiomers such as P6 1 and P6 5, the enantiomer of P622 is also P622 making the determination of the absolute chirality of the crystals a challenge. WebThe only exception from this rule is when "1" is used as a place holder in symmetry directions without other symmetry elements, as e.g. in space group P-3 1 2/m (#162). In …

WebThe KRCs represent 0.2% of the whole database and 0.8% of the chiral space groups. The KRC occurrence represents circa 1% (724 structures) of the set of racemic compounds. The distribution of the KRC space groups is drastically shifted toward lower symmetry space groups with a large prevalence of P2 1 structures. WebChirality domains can occur whenever the paramagnetic space group is centrosymmetric but the ordered magnetic structure is not. The centre of symmetry may be lost because magnetic moments on atoms at positions related by the centre are neither parallel or antiparallel to one another For example, suppose two atoms at vector distance ± r from a ...
