Structural Phase Transition in CeCuAl_{3} Single Crystal

Phase transition in single crystal Cs2Nb4O11.

We studied temperature dependence of complex capacitance, impedance, and polarized Raman spectra of single crystal Cs2Nb4O11. First, we observed a sharp lambda-shaped peak at 165 degrees C in the complex capacitance, then found drastic changes in the Raman spectra in the same temperature range. Utilizing the pseudosymmetry search of structure space group, we attributed the observed anomalies to...

A facile single crystal to single crystal transition with significant structural contraction on desolvation.

5-Ethynyl-1,3-benzenedicarboxylic acid (H2ebdc) reacted with lead(II) acetate trihydrate yields a 1D ladder network, [Pb(ebdc)(MeOH)]2·H2O (1). Removing crystals of 1 from the mother liquor results in a facile single crystal to single crystal transition, yielding 2D [Pb(ebdc)] net (2) with a change in space group from I2/a to P1̄.

Reversible Single-Crystal-to-Single-Crystal Phase Transition of Chiral Salicylidenephenylethylamine

The chiral crystal of enantiomeric (S)-N-3,5-di-tert-butylsalicylidene-1-phenylethylamine in the enol form [enol-(S)-1] undergoes a reversible single-crystal-to-single-crystal (SCSC) phase transition at Tc ≈ 3 ◦C from the room temperature α-form in orthorhombic space group P212121 (Z′ = 1) to the low temperature β-form in the monoclinic space group P21 (Z′ = 2) with a thermal hysteresis of appr...
