Special Issue Information

Dear Colleagues,

Binuclear and polynuclear metal complexes, such as 3d, 3d-4f and 4f complexes, have found applications in many different fields of fundamental and applied research, such as optics, DNA binding and cleavage, catalysis and molecular nanomagnetism. For single-molecule magnets (SMMs), nowadays, people desire to improve their remanence and coercivity of the hysteresis loops, the effective energy barrier (Ueff) and the blocking temperature (TB) by modulating the magnetic exchange couplings (for all polynuclear SMMs) and the axial symmetries and/or the charge distributions around LnIII ions (for binuclear and polynuclear 3d-4f and 4f SMMs, especially, containing Dy SMMs), which were verified many times by experimental and theoretical investigations. For catalysis, binuclear and polynuclear metal complexes offer the advantage of synthetic control over the steric and electronic properties in the vicinity of the active site. More recently, there has been a move towards exploiting these highly reactive complexes to achieve a range of catalysis in various organic reactions and small molecule activation, including the oxygen evolution reaction (OER), hydrogen evolution reaction (HER) and CO2 reduction reaction (CO2RR), etc.

In this Special Issue, we wish to publish research papers and reviews concerning the experimental studies and/or theoretical studies of SMMs and catalysis, including the binuclear and polynuclear 3d, 3d-4f and 4f complexes.

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. Inorganics 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 2700 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.

Abstract
Reaction of the 1,3-diisobutyl thiourea (L) with MX [M = Cu, Ag and X = Cl, NO3] provide polynuclear heteroleptic complexes [Cu3L3Cl3] (1), [Ag2L6](NO3)2 (2 [...] Read more.
Reaction of the 1,3-diisobutyl thiourea (L) with MX [M = Cu, Ag and X = Cl, NO3] provide polynuclear heteroleptic complexes [Cu3L3Cl3] (1), [Ag2L6](NO3)2 (2) and [Ag6L8Cl4] (3). All complexes were characterized by single crystal X-ray diffraction. The solid-state crystal of these complexes (13) were determined by single crystal XRD. Which shows that complex (1) is tri-nuclear with trigonal planer arrangement, complex (2) is binuclear with four membered metalacyclic ring and complex (3) is hexa-nuclear. Complexes (13) are tested for their free radical scavenging activity by using 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH) showing moderate potential. Full article
