Typical superalkalis include a central electronegative core with excess metal ligands. We propose a new series of non-metallic NnH3n+1+ superalkali cations using MP2/6-311++G(d,p) level. These cations are designed by successive replacement of H-ligands of ammonium cation (NH4+) by ammonium (NH4) moieties. The resulting NnH3n+1+ cations, which can be expressed in the form of [NH4 (n-1)NH3]+ complexes, possess a number of unusual N-H N type of partially covalent H-bonds, with the interacting energy in the"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.01215","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
