Abstrakt

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.
