Special Issue Information
Dear Colleagues,
The central and most interesting problem of modern inorganic chemistry is the reactivity of coordination compounds, especially in connection with such practically important tasks as the transformation of organic compounds into products that are useful and valuable to humans, activation of inert molecules, and study of photochemical processes (sunlight harvesting, generation of singlet oxygen, hydrogen production, photocatalysis etc). New practical needs combined with new capabilities for synthesis and characterization of coordination compounds put on the agenda the task of expanding the material basis of coordination chemistry, namely, synthesis and study of new and non-trivial classes of coordination compounds, in particular, cluster compounds having polymetallic cores with direct metal-metal interactions. In this case, we can expect to obtain compounds with a new, unexpected set of chemical and physical properties.
This special issue is devoted to various aspects of the chemistry of discrete molecular transition metal clusters, whose properties and applications very often differ from more familiar mononuclear compounds. Two main classes of clusters can be distinguished. They are low-valent or organometallic clusters, and high-valent or inorganic clusters (mainly chalcogenide and halide-bridged), which are characterized by great structural diversity and a plethora of potentially useful physico-chemical properties. These features are often combined with the stability of the cluster core (in ligand exchange processes and redox reactions) and the relatively simple modification of the ligand environment. Both types of clusters are considered as model objects for heterogeneous catalysts on metal surfaces (organometallic clusters) and metal chalcogenides (chalcogenide metal clusters). In addition, molecular clusters themselves are effective catalysts and can catalyze quite a few reactions better than momonuclear catalysts. In other words, molecular clusters are an intermediate link between mononuclear complexes and heterogeneous catalysts, and also represent a bridge between molecular and solid state chemistry. Their study opens up new prospects in material science, catalysis, and fundamental chemistry.

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. Molecules is an international peer-reviewed open access semimonthly 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.
