In this third part of our research on the 5,5′‐azobis[1 H ‐tetrazol‐1‐ides] (ZT) of the lanthanoids, we present two compounds with La 2 (ZT) 3 moieties with very different coordination modes between the cations and the anions. One La 2 (ZT) 3 ‐containing compound is interesting, because it contains trimeric La 3 (ZT) 3 III cations, which are arranged in a windmill‐like structure. Moreover, the first double salt of a ZT compound, namely the carbonate compound La 2 (ZT) 2 (CO 3 )⋅12 H 2 O, is presented and discussed. Another highlight of nitrogen chemistry is the first molecular structure of a 5‐azido‐2 H ‐tetrazole (CHN 7 ) molecule, in the form of the spectacular compound Dy 2 (ZT) 3 ⋅4 CHN 7 ⋅24 H 2 O. This is the first known complete molecular structure of an azidotetrazole molecule (the organic molecule with the highest nitrogen‐content: 88.3% N). All compounds have been characterized completely including elemental analyses, vibrational (IR and Raman ) spectroscopy, and X‐ray crystal‐structure determination. We summarize our ‘nitrogen‐rich compounds of the lanthanoids’ project and extensively discuss selected literature on this topic and compare previously published results with ours.
