Also, monoclinic crystals are spontaneously transformed into triclinic crystals within 6 months. It was shown that the presence of voids near one carboxylate ligand in the monoclinic phase of Ph3Sb-(O2CCH2−CH=CH2)2 decreases the energy of intermolecular interactions and, as a consequence, leads to a conformational transition with a noticeable decrease in the crystal lattice energy. Thus, the presence of voids in the monoclinic phase crystal allows the formation of a thermodynamically more favorable conformation of the molecule in the crystal. Several structural models were determined for the Ph3Sb(O2CCH2−CH=CH2)2 complex (CIF files no. 1887561 (IIAM), model of non-interacting atoms; 1887562 (I), multipole model; 1887563 (IIIAM), model of non-interacting atoms; 1887564 (II), multipole model).","is_dataset_classified":null,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19910364","pmcid":null,"openalex_id":"https://openalex.org/W2969184366","authors":[],"funders":[],"total_grants":0,"fwci":0.2011,"citation_percentile":0.43750915,"influential_citations":0,"citation_trend":[{"year":2020,"count":1},{"year":2021,"count":1}],"oa_status":"closed","license":"https://www.springernature.com/gp/researchers/text-and-data-mining","oa_locations":[{"url":"https://link.springer.com/content/pdf/10.1134/S1070328419080025.pdf","host_type":"publisher"},{"url":"https://link.springer.com/article/10.1134/S1070328419080025","host_type":"publisher"},{"url":"https://doi.org/10.1134/s1070328419080025","host_type":"journal"}],"fields_of_study":["Chemical Thermodynamics and Molecular Structure","Organometallic Compounds Synthesis and Characterization","Medicinal plant effects and applications"],"mesh_terms":[],"keywords":["Monoclinic crystal system","Triclinic crystal system","Crystallography","Chemistry","Lattice energy","Polymorphism (computer science)","Crystal (programming language)","Intermolecular force","Crystallization","Crystal structure","Molecule","Organic chemistry"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-03T06:21:23.373039Z","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":[]}
