A test of the importance of weak reflections in resolving a space-group ambiguity involving the presence or absence of an inversion centre

Acta Crystallographica Section B Structural Science, 1993
The structure of margarite, CaAl 2 [Al 2 Si 2 O 10 ](OH) 2 , has been reported in space group C2/c, and in the corresponding non-centrosymmetric space group Cc. Previous refinements of margarite in space group Cc were marred by strong correlations affecting parameters that are inversion related in C2/c.

Weak Z-Property of the Absolute Order on Groups Generated by Sets Closed Under Taking Inverses

Order, 2018
The author proves a result that implies that the absolute order satisfies a weaker version of the Z-property. The weak Z-property. Assume that \((G,R)\) is a pair satisfying certain properties and that \(\leq_R\) is its corresponding absolute order. Suppose that \(g,h \in G\) and \(r \in R\) with \(g \leq_ R r^{-1}g\) and \(rh \leq_R h\).
