Special Issue Information

Dear Colleagues,

In the last 20–25 years, metal complexes formed by chelating and macrocyclic organic and organo-element ligands (in particular, various crown ethers, cryptands, calixarenes, and porphyrins) have gained particular interest in coordination and inorganic chemistry. These compounds have a number of specific (sometimes unique) properties, due to which they have found many applications in various fields of science and in the practice of anthropogenic activities. In connection with this, it is important to predict their physicochemical parameters that determine these very properties, a problem that is currently being successfully solved thanks to the availability of modern quantum-chemical methods of calculation [and above all the density functional theory (DFT) method], as well as computer technologies and related experimental equipment. At the same time, in the literature there have been relatively few theoretical works devoted to quantum-chemical calculations of the above-mentioned metal complexes using the DFT method and more advanced methods.

Original full articles and short communications devoted to quantum-chemical calculations of metal complexes of p-, d-, and f-elements, with open and closed circuits formed by organic and organo-element ligands, are preferred for this Special Issue. We welcome articles in which, along with the required quantum-chemical calculations, experimental data is presented to evaluate the reliability of these calculations. Review articles may also be submitted for publication.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
The concept of “macrocyclic compounds” combines very different classes of chemicals that contain nine or more atoms in the macrocycle; macroheterocyclic compounds, the macrocycle of which contains at least one heteroatom, are also distinguished among them [...] Full article

By using quantum chemical calculation data obtained by the DFT method with the B3PW91/TZVP and OPBE/TZVP levels, the possibility of the existence of three Fe(V) complexes, each of which contains in the inner coordination sphere porphyrazine/trans-di[benzo]porphyrazine/tetra[benzo]porphyrazine (phthalocyanine), oxygen (O2−) and fluorine (F) ions, was shown. Key geometric parameters of the molecular structure of these heteroligand complexes are given; it is noted that FeN4 chelate nodes, and all metal-chelate and non-chelate cycles in each of these compounds, are practically planar with the deviation from coplanarity, as a rule, by no more than 0.5°. Furthermore, the bond angles between two nitrogen atoms and an Fe atom are equal to 90°, or less than this by no more than 0.1°, while the bond angles between donor atoms N, Fe, and O or F, in most cases, albeit insignificantly, differ from this value. Nevertheless, the bond angles formed by Fe, O and F atoms are exactly 180°. It is shown that good agreement occurs between the structural data obtained using the above two versions of the DFT method. NBO analysis data for these complexes are presented; it is noted that, according to both DFT methods used, the ground state of the each of three complexes under consideration may be a spin quartet or spin doublet. Additionally, standard thermodynamic parameters of formation (standard enthalpy ∆fH0, entropy S0 and Gibbs’s energy ∆fG0) for the macrocyclic compounds under consideration are calculated.
