Topical Collection Information

Dear Colleagues,

It is my great pleasure and honour as Collection Editor to announce a Topical Collection entitled "Reviews of Crystal Engineering".

The purpose of this Collection is to collect reviews related to the crystal chemistry of distinguished researchers; that is why this announcement has been directed to you.

Papers on all topics connected with crystal structures, the phenomena that occur in crystals, the intermolecular interactions in crystals, their different kinds of structures, the relationships between parameters describing molecular structures, etc., are welcome. In other words, all topics that are within the crystal engineering area or within the scope of crystal chemistry will be considered for publication in this Topical Collection.

One can see https://www.mdpi.com/journal/crystals/sections/crystal_engineering for the Crystal Engineering section information.

Prof. Dr. Sławomir Grabowski
Collection Editor

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 collection 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 2600 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.

Abstract
This review covers over fifty Pt(II) monomeric complexes with a wide combination of η3-ligands of the composition Pt(η3-X3L)(PL), (X3 = N3; S3; Te3; ONO; CNC, SeNSe; ONC; ONS; CNS; NNC, [...] Read more.
This review covers over fifty Pt(II) monomeric complexes with a wide combination of η3-ligands of the composition Pt(η3-X3L)(PL), (X3 = N3; S3; Te3; ONO; CNC, SeNSe; ONC; ONS; CNS; NNC, NNS; NNSe, SOS; SBS; NON; SSO). The η3-ligand with monodentate PL displays distorted square-planar geometry about Pt(II) atoms. The structural parameters (Pt-L, L-Pt-L) are analyzed and discussed, with a particular emphasis on the distortion of square-planar geometry about Pt(II) atoms, as well as of the trans-influence. There is a relation between the membered nature of the metallocycles and the distortion of square-planar geometry about the Pt(II) atoms. The distortion increases as indicated by parameter τ4 in the following order: 0.023 (6+6) < 0.024 (^+5) < 0.040 (5+6) < 0.062 (5+5). Full article

Abstract
The Cambridge Structural Database has been surveyed for crystals featuring organo-Hg···S secondary-bonding interactions within supramolecular aggregates. Nearly 50% of crystals where Hg···S interactions could potentially form, featured Hg···S contacts within zero- or one-dimensional supramolecular assemblies with only a few examples of two-dimensional arrays [...] Read more.
The Cambridge Structural Database has been surveyed for crystals featuring organo-Hg···S secondary-bonding interactions within supramolecular aggregates. Nearly 50% of crystals where Hg···S interactions could potentially form, featured Hg···S contacts within zero- or one-dimensional supramolecular assemblies with only a few examples of two-dimensional arrays featuring Hg···S interactions. This high propensity of Hg···S contact formation reflects the inherent thiophilic nature of mercury but also the relatively open access to mercury owing to the linear C–Hg–S coordination geometries, the prevalence of close intramolecular Hg···S, Hg···O and Hg···N interactions notwithstanding.

Although known since antiquity, mechanochemistry has remained dormant for centuries. Nowadays, mechanochemistry is a flourishing research field at the simultaneous stages of gathering data and (often astonishing) observations, and scientific argumentation toward their analysis, for which the combination of interdisciplinary expertise is necessary. Mechanochemistry’s implementation as a synthetic method is constantly increasing, although it remains far from being fully exploited, or understood on the basis of fundamental principles. This review starts by describing many remarkable advantages of mechanochemical reactions, simplifying and “greening” chemistry in solutions. This description is followed by an overview of the current main weaknesses to be addressed in the near future toward the systematic study of its energetics and chemical mechanisms. This review finishes by describing recent breakthrough experimental advances, such as in situ kinetics monitoring using synchrotron X-ray powder diffraction and Raman spectroscopy, plus equally significant computational chemistry approaches, such as quantum mechanochemistry, used for the understanding of covalent or hydrogen bond ruptures in biomolecules or mechanophores in polymers at the single-molecule level. Combined with new technologies to control temperature and pressure in ball mills, these appealing new methods are promising tools for establishing the fundamental knowledge necessary for the understanding of mechanochemical reactivity and mechanisms.
