Coordination Chemistry of Rare-Earth Metals

Dear Colleagues,

The rare-earth metals are a group of 17 elements including the 14 lanthanoids. They are special in that the core-like 4f orbitals are filled consecutively. They can all be trivalent exhibiting a similar behavior in coordination compounds, but one has to take the lanthanide contraction into account. Some elements (like cerium) can also adopt the tetravalent state. Much richer is the chemistry of reduced rare-earth compounds, with an alkaline-earth-like divalent state with only 4f orbitals occupied, and a variety of possibilities when an electronic configuration crossover from 4f to 5d appears. In organometallic compounds these divalent rare-earth ions can be isolated, in solid-state compounds cluster may form, in almost all cases encapsulating a main-group or transition-metal atom.

Work from all areas of rare-earth coordination compounds is welcome, not only synthesis and crystal structure determination but also work on (physical) properties related to crystalline materials. Routine structure determinations are discouraged.

Submission

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 quarterly journal published by MDPI.

Crystals has applied SCIE and has to wait the results for a while. The journal situation will get better and better with all related excellent scholars' efforts including yours.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 500 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
