A simple graphical method to pinpoint local pseudosymmetries in Z Z ′ > 1 cases

摘要

An intuitive method is presented for detecting pseudosymmetries in Z ′ 1 cases as a complement to well‐proven strategies already available in the literature. It is based in the simple idea that the mid‐points between equivalent atoms in symmetrically related molecules are disposed according to simple well‐known patterns, which are easily recognizable by optical inspection. A number of Z ′?= 4 cases in the literature are analyzed, which allows some of the potentialities of the method to be revealed.
