N2 - Second-generation cobalt and zinc coordination architectures were
obtained through efforts to stabilize extremely sensitive and energetic
transition-metal hydrazine perchlorate ionic polymers. Partial ligand
substitution by the tridentate hydrazinecarboxylate anion afforded
polymeric 2D-sheet structures never before observed for energetic
materials. Carefully balanced reaction conditions allowed the retention
of the noncoordinating perchlorate anion in the presence of a strongly
chelating hydrazinecarboxylate ligand. High-quality X-ray single-crystal
structure determination revealed that the metal coordination preferences
lead to different structural motifs and energetic properties, despite
the nearly isoformulaic nature of the two compounds. Energetic tests
indicate highly decreased sensitivity and DFT calculations suggest a
high explosive performance for these remarkable structures.
