TL;DR: In this paper, bimetallic extended networks built from WIV(CN)8−4− and M2+=FeII, CuII, denoted hereafter as FeW for FeII−2[WIV[CN]8]·8H2O and Cu ǫ-W for CuII-2]·5H 2O were solved in the tetragonal system for M=Fe, and consisted of a three-dimensional (3D) structure with alternating W(CN), 8 and Fe(H 2 O)2 units leading
Journal ArticleDOI
The first example of a centro-symmetrical bis(imido)-bridged dinuclear cobalt(III) complex: synthesis via oxidative dehydrogenation and phenoxazinone synthase activity.
TL;DR: This is the first example of a bis(imido)-bridged dinuclear cobalt(III) complex derived from metal-assisted oxidative dehydrogenation of the coordinated primary amine ligand and was found to be an excellent functional model for the phenoxazinone synthase.
Journal ArticleDOI
Design of an inversion center between two helical segments.
TL;DR: A new strategy is proposed to control the relative orientation of two folded helical oligomers in such a way that they diverge from an aromatic linker and have opposite helical handedness, which leads to the first designed meso-helices.
Journal ArticleDOI
High-pressure spin-crossover in a dinuclear Fe(II) complex

TL;DR: The very gradual pressure-induced spin crossover occurs between 7 and 25 kbar, and shows no evidence of crystallographic phase transitions, which is in stark contrast to the previously reported thermal spin crossover behaviour.
Journal ArticleDOI
Photomagnetism of a sym-cis-dithiocyanato iron(II) complex with a tetradentate N,N'-bis(2-pyridylmethyl)1,2-ethanediamine ligand.

TL;DR: A comprehensive study of the magnetic and photomagnetic behaviors of cis-[Fe(picen)(NCS)(2) ] (picen = N,N'-bis(2-pyridylmethyl)1,2-ethanediamine) was carried out, and the mechanism of the spin-crossover in this complex was revealed.
