Cyclo-N5\u2212 was used as a polynitrogen anion for the syntheses of energetic salts through metathesis reactions. Propamidinium (1), 5-amino-4-carbamoyl-1H-imidazol-3-ium (2), (1H-1,2,3-triazol-4-yl)methanaminium (3), 5-amino-4H-1,2,4-triazol-1-ium (4), 5-amino-3-methyl-4H-1,2,4-triazol-1-ium (5), and amino(pyrimidin-2-yl)methaniminium (6) pentazolates were obtained with high yields (&gt;80%), and their crystal structures were confirmed through single-crystal X-ray diffraction analyses. Hirshfeld surface analyses and 2D fingerprint plots generated by CrystalExplorer17 demonstrated that these compounds exhibited extensive hydrogen-bonding networks in their crystal packing. Mechanical sensitivity tests showed that all the prepared salts were highly insensitive (IS &gt; 35 J, FS &gt; 360 N), providing valuable insights for the further exploration of broader energetic materials containing cyclo-N5\u2212.<\/jats:p>","DOI":"10.3390\/molecules30122613","type":"journal-article","created":{"date-parts":[[2025,6,16]],"date-time":"2025-06-16T10:47:22Z","timestamp":1750070842000},"page":"2613","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Dense Hydrogen-Bonded Assembly of Hydrogen-Rich Cations and Pentazolate Anions: A Series of Highly Insensitive Ionic Salts"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9488-6730","authenticated-orcid":false,"given":"Lianghe","family":"Sun","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongwei","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9899-5795","authenticated-orcid":false,"given":"Shuaijie","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofeng","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoping","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6504-4405","authenticated-orcid":false,"given":"Yuangang","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2732","DOI":"10.1021\/ic200071q","article-title":"1,1\u2032-azobis(tetrazole): A highly energetic nitrogen-rich compound with a N10 chain","volume":"50","author":"Piercey","year":"2011","journal-title":"Inorg.
