Their potential to serve as activity fuels for hypergolic propellants and AP composite solid propellants was systematically evaluated. Thermal analysis and energy testing revealed that CBH-2 possesses a lower thermal decomposition onset temperature (191.8 \u00b0C) and a higher energy density (Ev = 29.51 kJ\u00b7cm\u20133), while both compounds exhibit low mechanical sensitivity and safety. In ignition tests with the liquid oxidizer WFNA, CBH-2 exhibited an ultrashort ignition delay time (8 ms), with a corresponding theoretical specific impulse of 241.4 s, significantly outperforming CBH-1 (26 ms, 190.9 s). Furthermore, when incorporated with ammonium perchlorate (AP) as a fuel component, CBH-2 exerts a more significant catalytic effect on the high-temperature decomposition of AP, reducing the peak decomposition temperature by 70.9 \u00b0C, and increasing the linear combustion rate of the composite system to 1.85 mm\u00b7s\u20131, approximately 3.2 times that of the CBH-1 system. Theoretical calculations revealed the root cause of these performance differences at the microscopic level: CBH-2 exhibits stronger intermolecular interactions and a narrower energy gap, indicating that the Co2+ center confers higher electron transfer capacity and intrinsic reactivity.<\/jats:p>","DOI":"10.1021\/acs.inorgchem.6c03005","type":"journal-article","created":{"date-parts":[[2026,8,10]],"date-time":"2026-08-10T16:02:24Z","timestamp":1786377744000},"page":"19506-19516","source":"Crossref","is-referenced-by-count":0,"title":["Metal Coordination\nCompounds Base on Cyanoborohydride\nand 2-Imidazolidinone: Activity Fuels for Hypergolic and AP\nComposite Propellant Applications"],"prefix":"10.1021","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-0464-7904","authenticated-orcid":true,"given":"Mingcheng","family":"Ge","sequence":"first","affiliation":[{"name":"Beijing Institute of Technology , , ,","place":["Beijing, China, 100081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Dai","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology , , ,","place":["Beijing, China, 100081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linna","family":"Liang","sequence":"additional","affiliation":[{"name":"North Institute of Science and Technical Information , ,","place":["Beijing, China, 100089"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinfeng","family":"Yan","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology , , ,","place":["Beijing, China, 100081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianguo","family":"Yang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology , , ,","place":["Beijing, China, 100081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7057-2862","authenticated-orcid":true,"given":"Jianguo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology , , ,","place":["Beijing, China, 100081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0972-952X","authenticated-orcid":true,"given":"Zhimin","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology , , ,","place":["Beijing, China, 100081"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,10]]},"reference":[{"issue":"9","key":"2026083104374190100_cit1","doi-asserted-by":"publisher","first-page":"4044","DOI":"10.1021\/cr068360d","article-title":"Synthesis of transportation fuels\nfrom biomass: chemistry, catalysts, and engineering","volume":"106","author":"Huber","year":"2006","journal-title":"Chem.
