The title compound, trans-[PdBr(2)(C(6)H(10)N(2))(2)], was synthesized ionothermally in the ionic liquid solvent 1-ethyl-3-methyl-imidazolium bromide. In the crystal, the Pd(II) atoms are square-planarly coordinated to two Br atoms and two neutral (C(6)H(10)N(2)) ligands. The Pd(II) atom is located on an inversion centre.

Methane trapped in the two distinct dodecahedral cages of the ionic clathrate hydrate of TBAB was studied by single crystal XRD and MD simulation. The relative CH4 occupancies over the cage types were opposite to those of CO2, which illustrates the interplay between the cage symmetry and guest shape and dynamics, and thus the gas selectivity.

We report a new lattice structure of the ionic clathrate hydrate of tetra-n-butylammonium bromide induced by guest CO2 molecules, which is found to provide high CO2 storage capacity. The structure was characterized by a set of methods, including single crystal X-ray diffraction, NMR, and MD simulations.

We developed a carbohydrate sensing material, which consists of a crystalline colloidal array (CCA) incorporated into a polyacrylamide hydrogel (PCCA) with pendent boronic acid groups. The embedded CCA diffracts visible light, and the PCCA diffraction wavelength reports on the hydrogel volume. This boronic acid PCCA responds to species containing vicinal cis diols such as carbohydrates. This PC...

Current United States Food and Drug Administration (FDA)-approved lithium salts are plagued with a narrow therapeutic window. Recent attempts to find alternative drugs have identified new chemical entities, but lithium's polypharmacological mechanisms for treating neuropsychiatric disorders are highly debated and are not yet matched. Thus, re-engineering current lithium solid forms in order to ...

Hyaluronan-binding protein 1 (HABP1)/p32/gC1qR was characterized as a highly acidic and oligomeric protein, which binds to different ligands like hyaluronan, C1q, and mannosylated albumin. It exists as trimer in high ionic and reducing conditions as shown by crystal structure. In the present study, we have examined the structural changes of HABP1 under a wide range of ionic environments. HABP1 ...

In this thesis, we present our studies on the structure and dynamics of novel Room-Temperature Ionic Liquids. Through our computer simulations we demonstrate that the kinetics of photo induced electron transfer reaction between S1 and S2 states of Crystal Violet Lactone in N-propyl-N-methylpyrrolidiniumbis(trifluoromethylsulfonyl)imide([Pr31][NTf2]) room temperature ionic liquid is local solven...
