[Rh(1H)3] shows two interpenetrating, homochiral rhombohedral networks linked by short carboxylate-carboxylic acid hydrogen bonds, in which each complex acts as a node for six hydrogen bonds. [Ru(1H2)(1H)2] forms only four such hydrogen bonds, leading to the formation of heterochiral chains held together by stacking between bipyridyls. [Co(2H)3] can in principle form six hydrogen bonds, but in practice forms only four in a layer structure where stacking interactions are important. This is attributed to differences in molecular shape.","is_dataset_classified":null,"base_score":3.912023005428146,"endowment":3.912023005428146,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"15252559","pmcid":null,"openalex_id":"https://openalex.org/W2114431227","authors":[],"funders":[],"total_grants":0,"fwci":4.4512,"citation_percentile":0.94359049,"influential_citations":0,"citation_trend":[{"year":2012,"count":6},{"year":2013,"count":3},{"year":2014,"count":7},{"year":2015,"count":2},{"year":2020,"count":2},{"year":2022,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://pubs.rsc.org/en/content/articlepdf/2004/DT/B314539E","host_type":"publisher"},{"url":"https://doi.org/10.1039/b314539e","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/15252559","host_type":"repository"},{"url":"http://irep.ntu.ac.uk/id/eprint/22242/","host_type":"repository"}],"fields_of_study":["Crystallography and molecular interactions","Metal-Organic Frameworks: Synthesis and Applications","Crystal structures of chemical compounds","2,2'-Dipyridyl","Cobalt","Crystallography, X-Ray","Hydrogen Bonding","Ligands","Models, Molecular","Molecular Structure","Organometallic Compounds","Ruthenium"],"mesh_terms":["Cobalt","Hydrogen Bonding","Ligands","Models, Molecular","Organometallic Compounds","Ruthenium","2,2'-Dipyridyl","Molecular Structure","Crystallography, X-Ray"],"keywords":["Stacking","Hydrogen bond","Chemistry","Carboxylate","Crystallography","Crystal structure","Crystal (programming language)","Trigonal crystal system","Crystal engineering","Molecule","Stereochemistry","Supramolecular chemistry","Organic chemistry"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-11T18:35:43.387698Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
