N2 - Four novel energetic complexes comprising furazan/nitramino groups were synthesized through a simple hydrothermal method. Owing to the introduction of an oxygen-containing nitramino group, Cu(DNAF)(NH3)3 (ECP-1), Cu(DNAF)(H2O)3 (ECP-2), Cu(ANFZ)2(H2O)5 (ECP-3), and Cu2(TA)2(H2O)6 (ECP-4) (DNAF = 4,5-dinitraminofurazan, ANFZ = 4-amino-3-nitraminofurazan, TA = 5-nitro-4-nitramino-1,2,3-triazole) possess relatively high oxygen contents and oxygen balance, indicating efficient energy release during the self-sustained redox process. In addition, these energetic coordination polymers (ECPs) possess exceptional crystal density and insensitivity to external stimuli. Compared to the energetic complexes reported previously, the oxygen balance and contents of nitrogen and oxygen atoms of ECP-1-ECP-4 remain at a relatively higher level (OB > −20%, N+O% > 60%), ECP-2 and ECP-4 have excellent positive oxygen balance (10.5% and 5.5%, respectively), and ECP-4 has the highest density (2.22 g/cm3) among these four coordination polymers.
