Five coordinated novel complexes of CuII and NiII have been synthesized from benzil and 1,3- diaminopropane-CuII/NiII complex and characterized by elemental analysis, i.r., n.m.r., e.p.r, molar conductance and u.v-vis, spectroscopy. The complexes are ionic in nature and exhibit pentaeoordinated geometry around the metal ion. The reaction kinetics of C25H36N5O2CuCl with calf thymus DNA was studi...

Four new NiII, CoII, ZnII, and CuII complexes with the promising anti-tuberculosis drug (E/Z)-N′-((5-Hydroxy-3,4-bis(hydroxymethyl)-6-methylpyridin-2-yl)methylene)-isonicotino-hydrazide (LH) were synthesized characterized by structural methods: single-crystal X-ray diffraction, vibrational spectroscopy, mass spectrometry. The ZnII metal ions form only amorphous phases various morphologies accor...

This paper reports on a series of five chiral Schiff base push-pull compounds derived from enantiomerically pure (1R,2R)-(?)-1,2-diaminocyclohexane. The NiII, CuII, ZnII and PdII complexes supported by ferrocene-containing unsymmetrically-substituted N2O2 quadridentate ligand were prepared via template reactions isolated in 74–87 % yields. A combination EA, IR, UV/vis 1H/13C{1H} NMR spectroscop...

Incorporation of heavy metal ions in cement hydrates is great interest for the storage and immobilization toxic, hazardous, radioactive wastes using cementitious matrix. Magnesium silicate hydrate (M-S-H) a low pH alternative binder to commonly used Portland cement. Low cements have been considered as promising matrix municipal nuclear waste last decades. It however crucial assure that incorpor...

the ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. in the present work, aggregation of the purified hemoglobinin adult (hba) and in fetus or newborn (hbf) in the presence of nitrite ions were studied.hemoglobin aggregation was perform...

In the title compound, [Ni(C13H18NO3)2(C12H8N2)], the NiII cation shows a distorted octa-hedral coordination environment. It is formed by two N atoms from the phenanthroline ligand, as well as two N and two O atoms belonging to two 2-[(2-hy-droxy-benz-yl)amino]-4-methyl-penta-noate ligands. Complex mol-ecules are connected into layers propagating along the ab plane via hydrogen bonds formed by ...

The asymmetric unit of the title compound, [Ni(H2O)6](C12H12BrN2O5S)2·H2O, contains a half hexa-aqua-nickel(II) complex cation with the NiII ion lying on an inversion center, one 5-bromo-7-[(2-hy-droxy-eth-yl)amino]-1-methyl-6-oxido-quinolin-1-ium-3-sulfonate (QAO) anion and a half lattice water mol-ecule on a twofold rotation axis. In the crystal, QAO anions are stacked in a column along the c...

By Captain C. C. DAS GUPTA, m.b., Chief Medical Officer, Hossainabad Group of Tea Estates, P. O. Gopalbagan, Jalpaiguri. Ljijution ant-Colo Niii, F. J. Palmer, in his article on " The treatment of cholera by cresol" published in the Indian Medical Gazette for August 1924, mentions that he tried cresol (Sanitol) in a small but severe outbreak of baciilary dysentery with satisfactory results. In ...
