| Abstract: | In this third part of our research on the 5,5′‐azobis1H‐tetrazol‐1‐ides] (ZT) of the lanthanoids, we present two compounds with La2(ZT)3 moieties with very different coordination modes between the cations and the anions. One La2(ZT)3‐containing compound is interesting, because it contains trimeric La3(ZT)3III cations, which are arranged in a windmill‐like structure. Moreover, the first double salt of a ZT compound, namely the carbonate compound La2(ZT)2(CO3)?12 H2O, is presented and discussed. Another highlight of nitrogen chemistry is the first molecular structure of a 5‐azido‐2H‐tetrazole (CHN7) molecule, in the form of the spectacular compound Dy2(ZT)3?4 CHN7?24 H2O. 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. |
