In the title compound, {[Zn(C(10)H(8)N(2))(H(2)O)(4)](C(8)H(4)O(4))}(n), the Zn(II) atoms, lying on a twofold rotation axis, are bridged by 4,4'-bipyridine ligands, resulting in a linear chain along the b axis. In the chain, the Zn(II) atom adopts a slightly distorted octa-hedral coordination geometry involving four water mol-ecules at the equatorial(More)
Novel chitosan/ZnO nanoparticle (CS/nano-ZnO) composite membranes were prepared via the method of sol-cast transformation and studied by UV-vis absorption spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray fluorescence spectrometry (EDX).

In the cation of the title compound, (C(15)H(20)N(2))[CdBr(4)], the dihedral angle between the two pyridine rings is 70.85 (5)°. An inter-molecular π-π inter-action between the pyridine rings [centroid-centroid distance = 3.900 (4) Å] is observed. The Cd(II) atom has a distorted tetra-hedral coordination.
In the title compound, C(8)H(7)N(3)O, there are two independent mol-ecules in the asymmetric unit, in which the angles between the pyridine ring and the isoxazole ring are 35.8 (6) and 10.6 (2)°. The crystal packing is stabilized by N-H⋯N hydrogen bonds, which result in the mol-ecules forming a two-dimensional supra-molecular layer.
