The CCDC statistics reveal that the P21/c space group is the most commonly found space group in Cadmium AZIDE complexes. However, there are several rare space groups present in these compounds, which have not been explored in detail. This mini-review aims to shed light on these uncommon space groups in cadmium AZIDE compounds, including I41/acd, R3̅, Pcca, and C2/m. Each space group is described in detail, and an example is presented for each to provide a better understanding of their unique properties. For instance, the I41/acd space group has a tetragonal crystal system with a unique four-fold symmetry axis, while the R3̅ space group belongs to the trigonal crystal system and has a three-fold axis of symmetry. Cd(N3)2 is used as an example for each space group to illustrate their characteristics. These findings offer valuable insights into exploring uncommon space groups in cadmium AZIDE compounds, which could lead to the creation of new materials with unique properties. This research could have significant implications for the development of advanced materials in various fields, including electronics, optics, and catalysis.
