Two novel nitrogen-rich lanthanide compds. of 5,5'-(azo bis)tetrazolide (ZT) were synthesized and structurally characterized. The dinuclear, isostructural compds. [Ce2(ZT)2CO3(H2O)12] · 4 H2O (1) and [Pr2(ZT)2CO3(H2O)12]·4H2O (2) were synthesized via two independent routes. Compd. 1 was obtained after partial Lewis acidic decompn. of ZT by CeIV in aq. soln. of (NH4)2Ce(NO3)6 and Na2ZT. Compd. 2 was obtained by crystn. from aq. solns. of Pr(NO3)3, Na2ZT, and Na2CO3. By X-ray diffraction anal. at 200 K, it was found that the trivalent lanthanide cations are bridged by a bidentate carbonato ligand and each cation is further coordinated by six H2O ligands and one ZT ligand thus being ninefold coordinated.
