Special Issue Information
Dear Colleagues,
Silicon, a heavier congener of carbon, has attracted researchers´ attention for a variety of reasons, including its ability to easily increase its coordination number to five or six. Over the past century, the exploration of silicon coordination compounds (so-called hypercoordinate Si-compounds) has gained momentum, and alongside the textbook example hexafluorosilicate ([SiF6]2), there has been a rapidly growing variety of compounds in which the Si atom formally exceeds the octet shell. Both tetra- and low-valent Si-compounds may achieve Si-hypercoordination such that Si-located lone pairs may also contribute to the formal exceeding of the octet shell. This multi-faceted field, in which researchers are equipped with information on a variety of Si oxidation numbers, coordination numbers and bonding partners, has given rise to the discovery and exploration of various Si‒X (where X = any kind of atom) bonding modes. Investigations in this field, such as the elucidation of molecular structures through crystallographic and computational means, as well as the exploration of bond stabilities and coordination equilibria, are accompanied by the development of hypercoordinate Si-compound applications, e.g., as reagents in organic syntheses. While some reviews summarize novel results obtained through the persistent exploration of silicon complexes, this Special Issue offers an overview of current activities in the field.

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 250 words) can be sent to the Editorial Office for assessment.
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.
