Special Issue Information
Dear Colleagues,
Covalent and noncovalent interactions are of vital importance in crystal chemistry, defining the principles underlying the self-assembly of molecules and the crystallization process. Noncovalent interactions, such as hydrogen bonds, halogen bonds, and CH···π and π···π interactions, dictate how molecules recognize each other and interact with their surroundings, and how they ultimately pack together into crystals. Covalent interactions, however, affect the assembly process in two ways. On one hand, molecular configuration and typical functional groups can be modified through covalent interaction control, which further results in a change in the noncovalent interactions in assemblies and crystals. On the other hand, it has been possible to covalently link the molecules in two- and three-dimensional (2D and 3D) organic structures, such as, for example, in metal–organic frameworks (MOFs) and covalent organic frameworks (COFs). Enhancing our knowledge of covalent and noncovalent interactions is crucial for explaining phenomena such as self-assembly, chemical reactivity, and crystallization.
Recently, significant progress has been made in the experimental and theoretical analysis of the influences of covalent and noncovalent interactions on crystal chemistry. A large quantity of advanced analysis methods, together with molecular simulation, have been applied for monitoring the assembly of the molecules, in which it was found that covalent and noncovalent interactions are critical factors influencing the packing mode of the molecules. Explaining the regulating effect of these interactions on the crystal structure adjustment and crystal chemistry has always been a long-standing objective. The present Special Issue, entitled “Covalent and Noncovalent Interactions in Crystal Chemistry, 3rd Edition”, invites status reports summarizing the progress achieved in recent years.

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.
