  • Coordination chemistry;
  • Organometallic chemistry;
  • Bioinorganic chemistry;
  • Solid-state chemistry;
  • Inorganic materials;
  • MOFs (metal–organic frameworks);
  • Energy;
  • Catalysis (including photo- and electro-catalysis);

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 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. Inorganics 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 2200 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.

Although spontaneous or complexation-induced reductions of CuII to CuI have occasionally been observed, controlling these processes remains a challenge. Herein, we report the synthesis of CuI complexes via the complexation-induced reduction of CuII complexes with pyridine-containing N4 Schiff-base ligand L incorporating a biphenyl unit (L = N,N’-([1,1′-biphenyl]-2,2′-diyl)bis(1-(6-methylpyridin-2-yl)methanimine)). Such a reduction has not yet been observed in previously reported CuII complexes with pyridine-containing N4 Schiff-base ligands, strongly suggesting that the torsional distortion of the ligand framework induced by the biphenyl moiety effectively promotes the complexation-induced reduction of CuII to CuI. The CuI complexes were thoroughly characterized by 1H NMR spectroscopy, UV–vis–NIR spectroscopy, and single-crystal X-ray diffraction analyses. The [CuI(L)]+ complex undergoes a reversible redox process with its oxidized species, which was identified as a CuII complex based on spectroelectrochemical measurements and theoretical calculations.
