The single crystal X-ray diffraction analysis performed at 150 K and 298 K reveals a relative increase in the unit cell parameter by 0.08%. The parameter at 300 K is refined by two independent procedures: in Bond’s scheme (a = 10.8152(9) Å, relative error Δa/a = 8·10–5) and by calibrating the equatorial circumference according to the external reference (a = 10.8145(6) Å, relative error Δa/a = 5.1·10–5). The values obtained coincide within the experimental error with data for the polycrystalline reference described by the National Bureau of Standards of the United States.

The obtained compound is characterized by elemental analysis and IR spectroscopy; its crystal structure is determined by XRD. The compound has a polymeric structure and is composed of {CuCl(L)} fragments connected into zigzag chains due to the coordination of the pyridine nitrogen of the L ligand of one fragment to the copper atom of the neighboring fragment. The copper ion has a distorted square-pyramidal coordination environment (∠NCuO = 155.71° and ∠NCuCl = 101.16°). The unit cell containing four {[Cu(L)Cl]·DMF} fragments is calculated within the quantum chemical approach of the density functional theory. The electronic structure is analyzed; the band structure and density of states diagrams are constructed. It is shown that the electronic structure has no band gap: the Fermi level virtually coincides with the highest occupied crystal orbital (HOCO) and is equal to –5.733 eV. The HOCO and the lowest unoccupied crystal orbital (LUCO) have similar compositions, but the contribution of p orbitals of the organic ligand is higher for the LUCO. The electron density Laplacian values at the critical points of Cu–N, Cu–Cl, and Cu–O bonds indicate that these bonds belong to the intermediate type with a predominant contribution of ionic bonding.","PeriodicalId":668,"journal":{"name":"Journal of Structural Chemistry","volume":"65 12","pages":"2533 - 2543"},"PeriodicalIF":1.2,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142890021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report ab initio (HF/6-31G) calculation data on the structure of an all-atom model of the cluster containing one ion pair of tetrabutylammonium bromide TBA+Br– in a vacuum and in a water environment. The same calculations are performed for its neutral structural analogue tetrabutylmethane (TBM). The following geometric parameters are reported: distances from the central atom to the terminal carbon and hydrogen atoms; distances between terminal atoms; excess charges on hydrogen atoms and angles between atoms characterizing the structure; volumes of structures approximating real species; average numbers and lengths of hydrogen bonds in water molecules depending on the distance to the central atom of the species. It is shown that the determined shapes correspond to irregular tetrahedra with densely packed hydrocarbon radicals.
