In this third part of our research on the 5,5'-azobis[1H-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)) center dot 12 H(2)O, is presented and discussed. Another highlight of nitrogen chemistry is the first molecular structure of a 5-azido-2H-tetrazole (CHN(7)) molecule, in the form of the spectacular compound Dy(2)(ZT)(3) center dot 4 CHN(7) center dot 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.
