Reactions of salicylaldehyde 4-methylthiosemicarbazone (H2L) and salicylaldehyde 4phenylthiosemicarbazone (H2L) with assorted chromium(III) precusors, [Cr(H2O)6]Cl3, [Cr(H2O)6](NO3)33H2O and [Cr(H2O)6](CH3COO)3, afforded new mononuclear chromium(III) complexes of the general formula [Cr(HL)2]X (X = Cl, NO3 and CH3COO). In all isolated compounds, Cr(III) ion is coordinated by the O,N,S atoms of...

The mononuclear ruthenium 1-Cl and dinuclear 2-Cl complexes undergo a photo-induced ligand exchange in water, affording the corresponding 1-H2O 2-H2O complexes. use of indium tin oxide nanoparticles (nanoITOs) to explore photo-electrochemistry situ-generated solution revealed greater photocurrents produced by these two when compared with an experiment using buffer only. Interestingly, high phot...

Two deoxyglucose (DG) derivatives, (α,β)-2-deoxy-2-amino(ethylcarbamate)-D-glucose (ECB-DG) and (α,β)-2-deoxy-2-amino(1,2-dihydroxypropyl)-D-glucose (DHP-DG), were synthesized and radiolabeled successfully with [99mTc(H2O)3(CO)3]+ complex. [99mTc]-ECB-DG and [99mTc]-DHP-DG complexes were prepared (96% and 93% radiochemical purities respectively) by using 46 mCi of Na99mTcO4 in 1 mL saline. Radi...

The crystal and molecular structures of [bis(5-chloro-2methoxybenzoate)tetraaquamanganese(II)], [pentaaqua(5-chloro-2-methoxybenzoato)cobalt(II)] (5chloro-2-methoxybenzoate), [pentaaqua(5-chloro-2-methoxybenzoato)nickel(II)] (5-chloro-2methoxybenzoate) and [aquabis(5-chloro-2-methoxybenzoate)zinc(II)] monohydrate were determined by a single-crystal X-ray analysis. Mn(H2O)4L2 (where L = C8H6ClO3...

In the reaction of zinc(II) sulfate and chloride salt 2-acetylpyridine-aminoguanidine, two types complex were obtained, i.e., [Zn(H2O)6](H2L)2(SO4)3·3H2O [Zn(L)H2O(SO4)]·H2O, depending on presence LiOAc as deprotonating agent. The physicochemical, structural, photoluminescence properties complexes examined. first complex, obtained in absence LiOAc, Schiff base had role a counter-ion its doubly ...

Two hydrated 5-azotetrazolyl salicylic acid (H3ASA) of [(H3ASA)·H2O] (1) and [(H3ASA)·4H2O] (2) and five H3ASA based dinuclear Ln(3+) complexes of {[Ln2(H1.5ASA)4(H2O)8]·6H2O} [Ln = Dy (3), Tb(4)], {[Gd2(H1.5ASA)4 (H2O)8]·5H2O} (5), {[Sm2(H1.5ASA)4(H2O)8]·6H2O} (6) and {[Eu4(H1.5ASA)8(H2O)18]·10H2O} (7) have been synthesized and characterized by single crystal X-ray diffraction analysis. In 1 a...

The work covers the formation of bisaldehyde ligand 2,2'-[ethane-1,2diylbis(oxy)] dibenzaldehyde (M) and its metal complexes. synthesis M was achieved via two steps in which equivalents salicylaldehyde were reacted with KOH an ethanolic medium. Subsequently, resulting compound dissolved DMF one equivalent 1,2-dibromoethane added. Adding solution chloride a range ions to 1:1 (M:L) mole ratio res...

We describe the publicly available data from the Global OZone Chemistry And Related trace gas Data records for the Stratosphere (GOZCARDS) project and provide some results, with a focus on hydrogen chloride (HCl), water vapor (H2O), and ozone (O3). This data set is a global long-term stratospheric Earth system data record, consisting of monthly zonal mean time series starting as early as 1979. ...

A series of novel Pd(ii) complexes with chelating mono(imidazolin-2-imine) and bis(imidazolin-2-imine) ligands were synthesized. The crystal structures of [Pd(DMEAIm(iPr))Cl2] and [Pd(DPENIm(iPr))Cl2] were determined by X-ray diffraction analysis. The reactivity of the six Pd(ii) complexes, namely, [Pd(en)Cl2], [Pd(EAIm(iPr))Cl2], [Pd(DMEAIm(iPr))Cl2], [Pd(DPENIm(iPr))Cl2], [Pd(BL(iPr))Cl2] and...
