In inorg. 5,5'-azobistetrazolate (C2N102-; ZT) compds., the energetic ZT moiety is usually stabilized by H-bonds to lattice H2O and/or coordination of an N-atom of the tetrazole ring to the metal ion. Here we present the synthesis and characterization of a novel, salt-like compd., [Dy(H2O)8]2ZT3, which constitutes a unique exception to the above rule. We used supercrit. CO2 as an unconventional desiccant in a straightforward metathesis reaction without abstaining from the benefits aq. chem. offers. It caused the crystn. of the title compd. with a complex system of H-bonds between [Dy(H2O)8]3+ and ZT2- that involves almost every N-atom of the ZT2- anions as H-bond acceptors, which sufficiently stabilizes the energetic ZT despite the lack of lattice H2O or a coordinative bond to the metal ion.
