A preliminary X-ray study of the title mol-ecular salt, [Ni(CH(4)N(2)S)(6)](NO(3))(2), has been reported twice previously, by Maďar [Acta Cryst. (1961), 14, 894] and Rodriguez, Cubero, Vega, Morente & Vazquez [Acta Cryst. (1961), 14, 1101], using film methods. We confirm the previous studies, but to modern standards of precision and with all H atoms located. The central Ni atom (site symmetry )...

In the title compound, C(10)H(12)ClN(3)S, the dihedral angle between the benzene ring and the thio-urea unit is 2.35 (19)°. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R(2) (2)(8) loops.

Differing caging mechanisms of electronically excited ICl within He...ICl complexes are investigated using laser-induced fluorescence and two-laser, pump-probe spectroscopy. A continuum signal is observed in laser-induced fluorescence spectra recorded with excitation energies that access regions above the I 2P3/2 + Cl 2P3/2 dissociation limit. We show that this signal is associated with transit...

We report the identification of heavy Rydberg resonances in the ion-pair spectra of I2, Cl2, ICl, and IBr. Extensive vibrational progressions are analysed in terms of the energy dependence of the quantum defect δ(Eb) rather than as Dunham expansions. This is shown to define the heavy Rydberg region, providing a more revealing fit to the data with fewer coefficients and leads just as easily to n...

OBJECTIVE To investigate whether longitudinal trajectories of inflammatory markers of asthma can be predicted by levels of family routines in youth with asthma. DESIGN Family routines were assessed through parent questionnaires and peripheral blood samples obtained from youth every 6 months throughout the 18-month study period. Longitudinal relationships were evaluated using hierarchical line...
