The structural studies reported here include anhydrous and hydrated nonhydrolyzed complexes, which were isolated alongside hydrolysis products, giving oxide/hydroxide lanthanide(III) dimers, tetramers, and ultimately hexamers. The compounds isolated include [Nd 2 Cl 6 (μ 2 -4-NH 2 -1,2,4-Triaz) 4 (4-NH 2 -1,2,4-Triaz) 2 ], [Ce 2 Cl 4 (μ 2 -Cl) 2 (μ 2 -4-NH 2 -1,2,4-Triaz) 4 ] n, [Ce 2 (μ 2 -Cl) 4 (μ 2 -OH) 2 (μ 2 -4-NH 2 -1,2,4-Triaz) 2 ] n, [Ln 4 Cl 4 (μ 2 -Cl) 4 (μ 3 -OH) 4 (μ 2 -4-NH 2 -1,2,4-Triaz) 4 ] n ·2 n H 2 O (Ln = Ce, Nd), and [Ce 6 Cl 6 (μ 6 -O 0.5 )(μ 3 -Cl 0.5 ) 4 (μ 3 -Cl 0.75 ) 3 (μ 3 -OH) 0.75 (μ 2 -4-NH 2 -1,2,4-Triaz) 12 ((OH 2 ) 0.25 ) 2 ] 2 [CeCl 6 ][Cl 9 ]· x H 2 O. In all complexes, all lanthanide atoms are pairwise connected via one or more 4-NH 2 -1,2,4-Triaz ligands and sometimes additional Cl – anions.","journal":"Crystal Growth & Design","year":2025,"id":524041,"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":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9443,"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":1396905,"name":"Geetha Bolla","orcid":"0000-0002-2726-8352","position":1,"is_corresponding":false},{"id":1396906,"name":"Ethan A.
