σ- and π-Hole Interactions in Crystals

Dear Colleagues,

Both σ- and π-holes are very effective models that enable us to underestand, and even predict, various chemical observations. For example, they can explain various modes of crystal packing, depending on which element(s) the crystal consists of. These concepts can even explain various chemical reactivities. On the σ-hole front, we can give insight intochalcogen bonding, pnictogen bonding, halogen bonding, etc. Many recent examples nicely account for sometimes unusual crystal packing, which could hardly be explained without taking the σ-hole and π-holes concepts into account.

We invite investigators to submit papers which discuss the development of crystal engineering in terms of σ- and π-hole concepts but the topics are rather flexible and submissions that consider either concept to any extent would be welcome.

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. 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 2100 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.
