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...

Crystallization from an aqueous methanol system composed of Ni(NO3)2, 2,2'-bipyridine (bpy) and LiTCNQ (TCNQ is 7,7,8,8-tetra-cyano-quinodi-methane) in a 1:3:2 molar ratio yielded single crystals of bis-[tris-(2,2'-bi-pyridine-κ2N,N')nickel(II)] bis-(7,7,8,8-tetra-cyano-quinodi-methane radical anion) bi[7,7,8,8-tetra-cyano-quino-dimethanide] hexa-hydrate, [Ni(C10H8N2)3]2(C24H8N8)(C12H4N4)2·6H2O...

The first instance of an acidic aqueous biphasic system (AcABS) based on tributyltetradecyl phosphonium chloride ([P44414 ][Cl]) and an acid is here reported. This AcABS exhibits pronounced thermomorphic behavior and is shown to be applicable to the extraction of metal ions from concentrated acidic solutions. Metal ions such as cobalt(II), iron(III), platinum(IV) and nickel(II) are found to par...

A method was developed for the separation of CdII, PbII, PtII, CoII, NiII, BiIII, CrII, CuII and HgII bis(2-hydroxyethyl)dithiocarbamate (HEDTC) complexes by micellar electrokinetic capillary chromatography. The complexes were formed by pre-capillary reaction of the metal ions with an excess of the ligand and then separated using a 100 mm borate buffer (pH 9.2) containing 4% methanol (v/v), 10 ...

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 ...

The cartoon figure on the cover image is Monkey King, who a character in classical Chinese novel “Journey to West”. He has 72 polymorphic transformations. As shown cartoon, he only needs blow breath and can create lot of little monkeys. p-Terphenylene-bridged NiII porphyrin dimer, which similar gave syn- anti-doubly heptagon-fused dimers, spiro-pentagon-bridged chlorin doubly octagon-fused dime...
