More than a century after its discovery, its chemistry remains poorly known and even basic questions are not yet satisfactorily addressed. In this work, we perform a systematic study of the geometries, interactions energies and bonding in basic polonium(IV) species, namely the hydrated [Po(H$_2$O)$_n$]$^{4+}$ and chlorinated [PoCl$_n$]$^{4-n}$ complexes by means of gas-phase electronic structure calculations. We show that while up to nine water molecules can fit in the first coordination sphere of the polonium(IV) ion, its coordination ","authors_text":"Florent R\\'eal, Nadiya Zhutova, R\\'emi Maurice, Val\\'erie Vallet","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.chem-ph","submitted_at":"2022-08-29T12:59:14Z","title":"Geometries, interaction energies and bonding in [Po(H$_2$O)$_n$]$^{4+}$ and [PoCl$_n$]$^{4-n}$ complexes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2208.13570","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:2ca67344e7040182c847ffb878224468a01415bd70f9815361c4a70898181bc8","target":"record","created_at":"2026-07-05T05:04:50Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"0beda3d0161f663d2b6992b7cdfcb5f4a20c971b5ce57febc8d8b934e9a13c5f","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.chem-ph","submitted_at":"2022-08-29T12:59:14Z","title_canon_sha256":"6ceca796d5f194f529a507aeb35a667e6710b3e4243635ab0131a3d901f873d8"},"schema_version":"1.0","source":{"id":"2208.13570","kind":"arxiv","version":3}},"canonical_sha256":"a7f58979d2caa07b19519164cf32645d5bf354625db08a11508a0b0a3347a314","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a7f58979d2caa07b19519164cf32645d5bf354625db08a11508a0b0a3347a314","first_computed_at":"2026-07-05T05:04:50.713195Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:04:50.713195Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lsFgCWw1mwwzj+fYBcPxoxNwN0g3dI4YBXlaNywBn7cjwNopo6LTfcVmksj2NV2AfWOXdncVfDZn4YTatNL6Bg==","signature_status":"signed_v1","signed_at":"2026-07-05T05:04:50.713714Z","signed_message":"canonical_sha256_bytes"},"source_id":"2208.13570","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2ca67344e7040182c847ffb878224468a01415bd70f9815361c4a70898181bc8","sha256:2e99a9475a3b2f85b75522fc8743a705fd148352d93b0ee0634ef070080e84b4"],"state_sha256":"5fdd8bdb1e41983b50887aecc7228e731cf092eb267f6dbcf41b3897f1ee243f"}
