Crystal structure and Hirshfeld surface analysis of tri-chlorido-(1,10-phenanthroline-κ ,')phenyltin(IV).

The title compound, [Sn(CH)Cl(CHN)], which was obtained by the reaction between 1,10-phenanthroline and phenyl-tin trichloride in methanol, exhibits intra-molecular hydrogen-bonding inter-actions involving the chlorine and hydrogen atoms. Crystal cohesion is ensured by inter-molecular C-H⋯Cl hydrogen bonds, as well as -⋯π and π-stacking inter-actions involving three different aromatic rings with centroid-centroid distances of 3.6605 (13), 3.

Versatile Reactivity of Mn Complexes in Reactions with N-Donor Heterocycles: Metamorphosis of Labile Homometallic Pivalates vs. Assembling of Endurable Heterometallic Acetates.

Reaction of 2,2'-bipyridine (2,2'-bipy) or 1,10-phenantroline (phen) with [Mn(Piv)(EtOH)] led to the formation of binuclear complexes [Mn(Piv)L] (L = 2,2'-bipy (), phen (); Piv is the anion of pivalic acid). Oxidation of or by air oxygen resulted in the formation of tetranuclear Mn complexes [MnO(Piv)L] (L = 2,2'-bipy (), phen ()). The hexanuclear complex [Mn(OH)(Piv)(pym)] () was formed in the reaction of [Mn(Piv)(EtOH)] with pyrimidine (pym), while oxidation of produced the coordination polymer [MnO(Piv)(pym)] ().

Isotopically enriched polymorphs of dysprosium single molecule magnets.

A triclinic polymorph Dy(t) and a monoclinic polymorph Dy(m) of [Dy(tta)(L)] with L = 4-[6-(1,3-benzothiazol-2-yl)pyridin-3-yl]-4',5'-bis(methylthio)tetrathiafulvene behave as Single-Molecule Magnets with hysteresis loops opened at zero field. Magnetic properties were enhanced through magnetic dilution and Dy isotopic enrichment which definitively support the importance of isotopes for the control of quantum magnets.

Thermal and near-infrared light induced spin crossover in a mononuclear iron(ii) complex with a tetrathiafulvalene-fused dipyridophenazine ligand.

A mononuclear Fe(ii) complex involving a tetrathiafulvalene-based ligand exhibits thermal spin-crossover (around 143 K) with pronounced hysteresis behaviour (48 K). The chromophoric and π-extended ligand allows Near-Infrared (NIR) sensitization for the light-induced excited spin-state trapping (LIESST) with T(LIESST) = 90 K.

Rational Design of a Lanthanide-Based Complex Featuring Different Single-Molecule Magnets.

The rational synthesis of the 2-{1-methylpyridine-N-oxide-4,5-[4,5-bis(propylthio)tetrathiafulvalenyl]-1H-benzimidazol-2-yl}pyridine ligand (L) is described. It led to the tetranuclear complex [Dy4(tta)12(L)2] (Dy-Dy2-Dy) after coordination reaction with the precursor Dy(tta)3⋅2 H2O (tta(-) = 2-thenoyltrifluoroacetonate). The X-ray structure of Dy-Dy2-Dy can be described as two terminal mononuclear units bridged by a central antiferromagnetically coupled dinuclear complex.
