2-Amino-5-methyl­pyridinium picolinate 0.63-hydrate

The asymmetric unit of the title compound, C(6)H(9)N(2) (+)·C(6)H(4)NO(2) (-)·0.63H(2)O, contains two crystallographically independent 2-amino-5-methyl-pyridinium cations, a pair of picolinate anions and two water mol-ecules, one with an occupancy of 0.25. Both the 2-amino-5-methyl-pyridine mol-ecules are protonated at the pyridine N atoms. In the crystal structure, the cations, anions and wate...

BA 14-2-bradley

This paper details the comparison of a built coupled volume concert hall and a computergenerated model of the hall. Coupled volume spaces typically have an auxiliary volume connected to the main volume through an acoustically transparent aperture. In this type of space, architectural parameters such as volume size and surface absorption can be designed to produce a non-linear reverberant decay,...

Crystal Structure and Nanoparticles of Dinuclear Silver(I) Complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2

Nanoparticles of a new dinuclear silver(I) complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2, where 4nb-tsc = 4-nitrobenzylidenethiosemicarbazone and PPh3 = triphenylphosphine, were prepared in an ultrasonic bath and characterized by FT-IR and SEM. The crystal structure of a suitable single crystal prepared by slow evaporation was determined by single crystal X-ray diffraction. The compou...
