Temperature and Pressure Dependence of the Crystal Structure of the Magnetic Molecular Conductor: (BEDT-TTF)₃CuBr₄

High-pressure polymorphism in L-serine monohydrate: identification of driving forces in high pressure phase transitions and possible implications for pressure-induced protein denaturation

“…Molecular solids typically have K 0 < 30 GPa, 66 and the following K 0 values are useful for comparison: Ru 3 (CO) 12 (6.6 GPa); salicylaldoxime (13.3 GPa), NaCl (25 GPa), cystine (29.1 GPa), quartz (37 GPa), ceramics (50-300 GPa) and diamond (440 GPa). 24,40,67 The structure of L-serine monohydrate-I at 3.8 GPa was derived from a joint X-N refinement against single-crystal (20) are graph set descriptors of hydrogen bonding motifs. C(5) refers to a chain motif where the repeat unit in the chain is five atoms in length; R 4 4 (20) refers to a 20-membered ring motif containing four H-bond donors and four H-bond acceptors.…”

“…Research has been carried out on pressure-induced polymorphism in simple organic compounds such as formic 1 and acetic acids, 2 methanol, 3 ethanol, 2,4 phenols [5][6][7] and acetone 8 and on more complex systems such as hydrogen-bonded systems, [9][10][11][12] amino acids, 13 pharmaceuticals, energetic materials, 14 metal carbonyls, 15 spin cross-over complexes, 16,17 molecular conductors [18][19][20] and even single molecule magnets, 21 which may contain 100 atoms per molecule. At the far extreme in terms of the size of system that can now be studied, high-pressure protein crystallography is a rapidly developing field.…”

High-Pressure Single-Crystal Techniques

“…Although the beryllium gasket material allows this relatively free access to reciprocal space, it suffers the major disadvantage of limiting the pressure that the cell can achieve to around 3.5 GPa. Nevertheless, successful studies of low-symmetry materials have been undertaken with great success, see for example Guionneau et al (1996).…”

Structural Properties of the Superconducting Salt (BEDT-TTF)3Cl2·(H2O)2 at Low Temperatures

“…AuBr (11), and (BEDT-TTF) CuBr (13). The c parameter, corresponding almost to the BEDT-TTF molecular axis and the perpendicular to the layers, does not change with temperature.…”
