Special Issue Information

Dear Colleagues,

Coordination compounds exhibit many interesting properties, which find diverse applications in many aspects of human life. Often, the symmetric and/or asymmetric architecture of molecules determines their physical–chemical properties.

The goal of this Special Issue is, therefore, to solicit and publish the latest advances in the molecular design of new molecules with symmetrical or nonsymmetrical architecture formed by noncovalent bonds (ionic, H-bridge, charge transfer, hydrophobic, and hydrophilic interactions) and to inform researchers in the related fields of its potential application. Additionally, the aim of this issue is to highlight aspects of symmetry and asymmetry in supramolecular space, self-assembly, and interesting physicochemical properties, all of which cover the breadth of what makes this branch of chemistry such a diverse and exciting field of research. The progress of this new field has helped to blur the traditional borders between inorganic and organic chemistry through the isolation of numerous compounds consisting of metal ions and organic ligands.

We would like to collect studies on such topics as the influence of the symmetrical or nonsymmetrical architecture of molecules on the supramolecular self-assembly and aggregations of coordination compounds and organic ligands.

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. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). 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.

The Fe(III) complexes of branched asymmetric dendrimers were obtained by a one-step reaction as the second-generation architectures. Mesomorphic behavior was found for complexes with PF6 and BF4 counter-ions. To obtain knowledge about the existence of HS and LS fractions of iron(III) ion and their evolution with temperature, EPR methods were used. It was demonstrated that compounds contain one low-spin (LS, S = 1/2) and two HS-spin (HS, S = 5/2) of Fe(III) centers and are packed into two magnetic sub-lattices. A floating layers of Fe(III) complexes and Langmuir–Blodgett films on their base were formed and investigated in the presence of a magnetic field. Full article
