“…With basic Ln salts, the LnÀ(OH) À bond lengths are ca. 0.1 shorter than the respective LnÀOH 2 bond lengths (cf., e.g., [39]). Disregarding the bonds of La to the XO 3 ligand, the LnÀO bond lengths of 4, however, fluctuate within a range of ca.…”

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 ) · 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 · 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.

“…Most of the porous coordination polymers reported so far involved 3d metal ions and there is only a few examples involving lanthanide ions [1,[5][6][7][8]. Even more, despite great efforts in synthesizing lanthanide-based polynuclear complexes [9][10][11][12][13][14][15][16][17], very few coordination polymers exhibiting polynuclear entities as metallic cores have been reported so far [18,19] because most of these polynuclear complexes are unstable in solution [12]. For a few years our group has developed a family of more stable hexanuclear complexes [18,20] (see Scheme 1) and is currently working on the design of new coordination polymers in which the metallic centers are no longer single lanthanide ions but hexanuclear complexes [18].…”

“…the trihydrate (Riess, 2012). In addition, basic oxo-hydroxo-nitrate hydrates are known with Tm (Giester et al, 2009). The thulium nitrate pentahydrate adopts the Y(NO 3 ) 3 Á5H 2 O type of structure (Eriksson, 1982;Klein, 2020), and is isotypic with the respective Eu (Ribá r et al, 1986), Gd (Stockhause & Meyer, 1997), Dy, Er, Yb (Junk et al, 1999) and Ho compounds (Rincke et al, 2017).…”

Tm(NO3)3·5H2O and Tm(NO3)3·6H2O, or more precisely [Tm(NO3)3(H2O)4]·H2O and [Tm(NO3)3(H2O)4]·2H2O, respectively, have been obtained from a concentrated solution of Tm2O3 in HNO3. The crystal structures of the two hydrates show strong similarities as both crystallize in space group P\overline{1} with all atoms at general positions and contain neutral, molecular [Tm(NO3)3(H2O)4] complexes, i.e. ten-coordinated TmIII cations with three nitrate anions as bidentate ligands and four coordinating water molecules, and one or two additional crystal water molecules, respectively. All building units are connected by medium–strong to weak O—H...O hydrogen bonds. Tm(NO3)3·6H2O represents the maximally hydrated thulium nitrate as well as the heaviest rare earth nitrate hexahydrate known to date.
