In this paper, ammine lithium borohydride (LiBH(4)·NH(3)) was successfully impregnated into multi-walled carbon nanotubes (CNTs) through a melting technique. X-ray diffraction, scanning electron microscopy, Brunauer-Emmett-Teller, and density measurements were employed to confirm the formation of the nanostructured LiBH(4)·NH(3)/CNTs composites. As a consequence, it was found that the dehydroge...

The whole mol-ecule of the title compound, [NiCl2(C3H4N2)2(NH3)2], is generated by inversion symmetry. The Ni(II) ion, which is located on an inversion center, has a distorted octa-hedral coordination environment and is surrounded by two ammine N atoms and two Cl atoms in the equatorial plane, with two N atoms of two imidazole groups occupying the axial positions. The imidazole ring makes a dih...

In the title compound, [Ag(NH(3))(2)](2)(C(8)H(3)NO(6))·H(2)O, the cations have an almost linear coordination geometry with two ammine ligands and inter-act with the water mol-ecules [Ag⋯O(water) = 2.725 (4) and 2.985 (4) Å]. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds, combined with weak (lone pair)⋯π [O⋯centroid distance = 3.401 (4) Å] and π-π stacking [centroid-centroid distance = 3.975 (...

The observation of Manchot? that sodium pentacyano-ammineferroate2 I absorbs oxygen has led Baudisch and his coworkers3 to study the catalytic action of this salt, as well as of its water analogue II, in the oxidation of pyrimidines and purines. The present authors have previously reported in this journal4 on the nature of the oxidation products obtained. In the present paper the problem is con...

Single crystal and powder X-ray diffraction have been used to examine the host-guest complex of cucurbit[7]uril (CB[7]) and the model dinuclear platinum anticancer complex trans-[{PtCl(NH(3))(2)}(2)mu-dpzm](2+) (di-Pt, dpzm= 4,4'-dipyrazolylmethane). The single crystal structure shows that the host-guest complex forms with the di-Pt dpzm ligand within the CB[7] cavity and with the platinum grou...

The Balbiani Rings (BR) in the polytene chromosomes of Chironomus salivary glands are intense sites of transcription. The nascent RNPs fold during transcription into 40-50-nm granules, containing in the mature transcript approximately 37-kb RNA. Using a new nucleic acid specific stain, osmium ammine B on Lowicryl sections, in combination with electron energy filtered imaging of sections contain...
