In the title compound, [Cu(C(6)H(10)NS(2))I(C(10)H(8)N(2))], the Cu(II) ion is coordinated by one iodide ion, two N atoms of the bipyridine ligand and two S atoms from the piperidine-carbodithio-ate ligand in a distorted square-pyramidal environment. π-π stacking inter-actions, with centroid-centroid distances of 3.643 (4) Å, between pyridyl rings of the bipyridyl ligands of neighbouring mol-ec...

Ultrafast photodissociation dynamics of n-butyl iodide in the A-band has been studied by femtosecond time-resolved mass spectroscopy coupled with ion imaging. The time constant of n-C4H9I in the A-band with one photon excitation at ∼267 nm is measured to be ∼(58±6) fs. The ion images of I (P3/2) and I ∗ (P1/2) at ∼267 nm and ∼274 nm are obtained and analyzed to yield corresponding speed and ang...

In the mononuclear title complex, [CuI(C(6)H(8)N(2)S)(C(18)H(15)P)(2)], the Cu(I) ion is in a slightly distorted tetra-hedral coordination geometry formed by two P atoms from two triphenyl-phosphane ligands, one S atom from a 4,6-dimethyl-pyrimidine-2(1H)-thione ligand and one iodide ion. There is an intra-molecular N-H⋯I hydrogen bond. In the crystal, π-π stacking inter-actions [centroid-centr...

Despite prolonged scientific efforts to unravel the effects of ions on the structure and dynamics of water, many open questions remain, in particular concerning the spatial extent of this effect (i.e., the number of water molecules affected) and the origin of ion-specific effects. A combined terahertz and femtosecond infrared spectroscopic study of water dynamics around different ions (specific...

We use the photofragment ion imaging technique to investigate the 266-nm photodissociation dynamics of hydrogen iodide. We show the quantitative features of ion imaging by comparing determinations of photofragment recoil velocity distributions, product branching ratios and the HI bond dissociation energy with previously published results. Excellent agreement with previous experimental and theor...
