Fe2O3, pseudobrookite crystals were found to coexist with rutile‐type MO2‐δ (M=Ti, Fe) with extended defects. These are composed mainly of (121)r and (132)r crystallographic shear planes (CSP`s), where the r sub‐index refers to the rutile subcell. For samples with a lower Fe2O3 content (2, 1, 0.5% mol) only iron‐doped rutile phases were observed, with complex microstructure arising from the presence of multi‐twinned (011)r and (110)r crystals and isolated and/or ordered CSP`s at short length scale. The diverse microstructures observed in the CO2 laser produced samples correlate with the conditions imposed during the laser treatment, which include intrinsically high solidification rates and steep temperature gradients.","PeriodicalId":23934,"journal":{"name":"Zeitschrift für anorganische und allgemeine Chemie","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141863285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crystallographic analysis revealed that complex 1 has seesaw geometry with HL coordinated as a bidentate ligand to a metal ion. The role of weak forces like π∙∙∙π and CH∙∙∙π interactions in influencing the self‐assembly process appears to be of importance. The electronic structure of the complex was predicted using DFT calculations with mixed basis set. DFT calculated structural parameters are in good agreement with the experimentally obtained parameters from XRD. Molecular reactivity and stability of the complex has been assessed through frontier molecular orbital analysis. Evaluation of molecular electrostatic potential (MEP) displaying the electrophilic and nucleophilic reactivity sites. The Hirshfeld surface analysis clearly indicates CH∙∙∙π interaction and π∙∙∙π stacking interactions are responsible to extend the supramolecular network of the complex.

NMR spectroscopy for all compounds and single‐crystal X‐ray crystallography for 3 and 4 a, b enabled a clear structural characterization. Single crystal X‐ray analysis of 3 showed a dimeric structure, where two THF‐molecules and three hydrides from the BH3‐group contribute to the coordination sphere of the lithium atom. Interestingly, crystals suitable for X‐ray analysis of 4 a and 4 b showed a solvent‐free cluster formation, due to the coordination of the MeO groups. Both species form coordination polymers with different coordination modes depending on the nature of the alkali metal.

The crystal structure was solved from single‐crystal X‐ray diffraction data: Tl2Pb(SO4)2 crystallizes in space group R[[EQUATION]]m with lattice parameters of a = 5.5955(2) Å, c = 22.1001(9) Å, and Z = 3, which is also corroborated by Rietveld refinement on X‐ray powder data. The crystal structure can be regarded as [Pb(SO4)2]2‐ sheets intercalated by double layers of Tl+ along the c‐axis. From a mineralogical perspective, Tl2Pb(SO4)2 belongs to the palmierite family and can further be classified within palmierite‐supergroup. Validation of the structure models was carried out utilizing various concepts including Bond Valence (BV), Charge Distribution (CD) and Madelung Part of Lattice Energy (MAPLE). Notably, a contrast in stereochemical activity of 6s2 lone electron pair (LEP) between Tl+ and Pb2+ is interpreted in terms of bonding behaviours as well as Wang‐Liebau Eccentricity (WLE) parameters. Moreover, an extensive investigation into the crystal chemistry of thallium‐containing sulfates was conducted for the first time, focusing on the coordination environment and bonding behaviour of Tl+ and corresponding WLE parameters. A comparative analysis of these structurally related compounds including Tl2Pb(SO4)2, Tl3H(SO4)2, TlBi(SO4)2, TlIn(SO4)2, TlRh(SO4)2, and TlAl(SO4)2 was delineated.","PeriodicalId":23934,"journal":{"name":"Zeitschrift für anorganische und allgemeine Chemie","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141773025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
