Special Issue "Crystal Structures of Compounds Containing Ions Selenite"
Deadline for manuscript submissions: closed (20 March 2018)
The chemistry of materials containing chalcogen elements, and in particular Se oxyanions in the +4 oxidation state, is of increasing interest to the research community for several reasons: First, it is known that the incorporation of selenite anions can lead to non-centrosymmetric structures and, consequently, to materials displaying remarkable non-linear optical properties, ferroelectricity and piezoelectricity. Moreover, the lone pair on the chalcogen atom could behave as structure-directing agent towards the formation of materials characterized by the presence of hollows or channels in their intimate structures. Moreover, some selenites show highly robust three-dimensional open framework structures, which are retained on the removal of guests or coordinated little molecules. In fact, porous structures, due to the presence of the lone pair on the chalcogen atom, open the utilization of selenite derivatives in the synthesis of Metal Organic Frameworks (MOFs) or Porous Coordination Polymers (PCPs). In addition, when selenite anions act as bridging ligands towards metal atoms, they can hold (keep) close the cationic centers, allowing magnetic exchange between paramagnetic metals. Finally, the weakly coordinative capability of the Se(IV) electron lone pairs could give rise to supramolecular interactions.
For all these reasons a high potential interest on materials containing ion selenites is expected, even though relatively few studies on such compounds have been reported until now. The most important feature is that the full comprehension of the properties of this type of materials cannot be exhaustively understood unless the complete solid state crystal structure is available. In this Special Issue, of which the theme is “Crystal Structures of Compounds Containing Ions Selenite”, we aim to collect a series of examples showing the fundamental role of detailed structural analysis in understanding the interactions in the solid state responsible for the peculiar chemical physical properties of such materials.

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 papers will be 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. Crystals 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 1200 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.
