Anion-Induced Self-Assembly of Luminescent and Magnetic Homoleptic Cyclic Tetranuclear Ln₄(Salen)₄ and Ln₄(Salen)₂ Complexes (Ln = Nd, Yb, Er, or Gd)

Unique homoleptic cyclic tetranuclear Ln4(Salen)4 complexes [Ln4(L)2(HL)2(μ3-OH)2Cl2]·2Cl (Ln = Nd, 1; Ln = Yb, 2; Ln = Er, 3; Ln = Gd, 4) or Ln4(Salen)2 complexes [Ln4(L)2(μ3-OH)2(OAc)6] (Ln = Nd, 5; Ln = Yb, 6; Ln = Er, 7; Ln = Gd, 8) have been self-assembled from the reaction of the hexadentate Salen-type Schiff-base ligand H2L with LnCl3·6H2O or Ln(OAc)6·6H2O (Ln = Nd, Yb, Er, or Gd), respe...

Structure Symmetry Determination and Magnetic Evolution in Sr₂Ir_{1−<em>x</em>}Rh_<em>x</em>O₄

Melting of Forsterite, Mg₂SiO₄, From 9.7 to 16.5 GPa

A multianvil apparatus ha been used to determine th pressure-temperature mel ing curve of forsterite from 9.7 to 16.5 GPa. At 10.1 GPa a singular point occurs that marks the change from congruent melting at lower pressures to incongruent melting (forsterite periclase + liquid) at higher pressures. The melting curve also passes through two invariant points. At one (15.6 GPa, 2310øC), the phases ...

A Novel Phase of Li₁₅Si₄ Synthesized under Pressure

However, in situ X-ray diffraction (XRD) studies on the lithiation /delithiation of Si anodes confi rmed the absence of the above-mentioned stable compounds in the electrochemical reaction in Li-ion batteries at room temperature. [ 12,13 ] The only crystalline lithium silicide formed is Li 15 Si 4 (space group 43 I d), a metastable phase that decomposes to Li 13 Si 4 , Li 17 Si 4 /Li 4.11 Si, o...
