Abstract This work is supplement to our previous investigation (Gazhulina and Marychev, 2015) [1]. We have considered pseudosymmetric features with respect to the operation of inversion (pseudoinversion) for 340 non-centrosymmetric AB type crystals. Analysis of the features of particular structure types allowed us to determine the positions of pseudoinversion centers, subdivide them into separate types, and classify the entire set of crystals studied with respect to the types of pseudoinversion centers and peculiarities of the behavior of the degree of pseudoinversion depending on the ratio of atomic numbers of A and B components. For each group of crystals, average values and lower boundaries of the maximum pseudoinversion are determined and distribution with respect to the degree of pseudoinversion is constructed. - Graphical abstract: A group of 340 non-centrosymmetric AB type crystals have been considered for their pseudosymmetry features with respect to the operation of inversion. Positions of pseudoinversion centers, subdivision of them into separate types, classification of the entire set of crystals studied with respect to the types of pseudoinversion centers and peculiarities of the behavior of the degree of pseudoinversion are established and discussed. Display Omitted - Highlights: • We consider pseudoinversion of 340 non-centrosymmetric AB type crystals. • AB type crystals are divided into three groups with respect to pseudoinversion. • Positions and types of pseudoinversion centers are determined. • Lower boundaries of the maximum pseudoinversion are determined.
