Owing reduced lattice vibrations shrunken average distance Eu(II)‐iodide bonds in face‐sharing...

Abstract A dual‐function material in which ferroelectricity and spin crossover coexist the same temperature range has been obtained. Our synthetic strategy allows construction of acentric crystal structures a predictable way is based on high directionality hydrogen bonds. The well‐known iron(II) complex [Fe(bpp) 2 ] 2+ (bpp=2,6‐bis(pyrazol‐3‐yl)pyridine), four‐fold noncentrosymmetric H‐bond donor, was combined with disymmetric acceptor such as isonicotinate (isonic) anion to afford ](isonic)...
Although metal oxide nanocrystals are often highly active, rapid aggregation (particularly in water) generally precludes detailed solution-state investigations of their catalytic reactions. This is equally true for visible-light-driven water oxidation with hematite α-Fe2 O3 nanocrystals, which bridge a conceptual divide between molecular complexes iron and solid-state photoanodes. We herein report that the aqueous solubility remarkable stability polyoxometalate (POM)-complexed cores 275...
Searches for planar hexacoordinate carbon (phC) species comprised of only seven atoms uncovered good CX3M3 prototypes, D3h CN3Be3+ and CO3Li3+. The latter is the global minimum. It might also be possible to detect deep-lying kinetically-viable local minimum, based on its robustness toward molecular dynamic simulations very high isomerization barrier.

Indeed, so-called clock transitions have been shown protect molecular qubits noise, giving rise significantly enhanced Here we conduct a spectroscopic and...
Following the isoelectronic relationship in global minima planar pentacoordinate carbon (ppC) species (cationic CAl(5)(+), neutral CAl(4)Be, and monoanionic CAl(3)Be(2)(-)), we designed a dianionic ppC C(2v) CAl(2)Be(3)(2-) (1a) its salt complex LiCAl(2)Be(3)(-) (2a) this work.

A new iron-oxalato polyoxometalate exhibits a remarkable photocoloration effect in the solid state based entirely on an intramolecular process.
Polyoxometalate (POM) chemistry has recently offered excellent examples of single ion magnets (SIMs) and molecular spin qubits. Compared with conventional coordination compounds, POMs provide rigid highly symmetric sites. However, all POM-based SIMs reported to date exhibit a very limited range possibilities for chemical processability. We present herein two new families which are soluble in organic solvents: [Ln(β-Mo8O26)2]5- {LnIII = Tb, Dy, Ho, Er, Tm Yb} the functionalised...
