{"doi":"10.1107/s2053229625003584","title":"Synthesis and crystal structures of a family of bimetallic complexes with phenyl-substituted bridging tetraoxolene ligands","abstract":"Seven dinuclear metal complexes and one trinuclear metal complex have been synthesized using the redox-active diphenyl-substituted tetraoxolene 2,5-dihydroxy-3,6-diphenyl-1,4-benzoquinone (H 2 Ph 2 dhbq, C 18 H 12 O 4 ) as a bridging ligand and tris[(pyridin-2-yl)methyl]amine (TPA, C 18 H 18 N 4 ) as a tetradentate terminal ligand. Single-crystal X-ray diffraction data confirm the final redox states of all components, revealing both expected and unexpected redox behavior across the eight reported complexes. Metal complexes with the formula [ M II 2 (Ph 2 dhbq 2− )(TPA) 2 ] 2+ can be synthesized from Mn, Fe, Co, Ni, Zn, and Ru, using either the oxidized ligand H 2 Ph 2 dhbq or a combination of the reduced ligand H 4 Ph 2 dhbq and an in-situ oxidant. Additionally, switching to Group 13 elements, such as Ga, facilitates the formation of the related [ M III 2 (Ph 2 dhbq 4− )(TPA) 2 ] 2+ complex, wherein the ligand remains in its initial reduced state.","journal":"Acta Crystallographica Section C Structural Chemistry","year":2025,"id":544156,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9502,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1399612,"name":"Phuong H.
