The complexes containing mixed of ligands [5-(3-chlorophenyl) -1,3,4-oxadiazole-2-thione(CPoxSH)] and diphosphines Ph2P(CH2)nPPh2 (diphos)(n=1-4), are prepared by the reaction [Hg(CPoxS)2] or [M(H2O)2(CPoxS)2] (M = Co, Ni ) with one mole proportion diphosphine gave tetrahedral type [Hg(CPoxS)2(diphos)]. While an octahedral cobalt(II) nickel(II) ions [M(H2O)(CPoxS)2(diphos)] when Co receptivity....

ABSTRACT. Adrenaline complexes with bivalent ions Mg2+, Ca2+, Sr2+ and Ba2+ in methanol at 60 oC were prepared. The prepared isolated characterized using elemental analyses, conductivity measurements, mid infrared, Raman laser, UV-Vis., 1H–NMR spectra, X-ray powder diffraction, scanning electron microscopy energy-dispersive spectroscopy (EDX). Upon the spectroscopic, stoichiometric reactions in...

Throughout the Earth’s history, mass transport involved fluids. In order to address the circumstances under which Zr may have been transported in this manner, its solubility behavior in aqueous fluid with and without NaOH and SiO2 in equilibrium with crystalline ZrO2 was determined from 550 to 950 °C and 60 to 1200 MPa. The measurements were carried out in situ while the samples were at the tem...

While the catalytic activity of some Ru-based polypyridine complexes in water oxidation is well established, the relationship between their chemical structure and activity is less known. In this work, the single site Ru complex [Ru(bpy)2(H2O)2] (bpy = 2,2′-bipyridine)—which can exist as either a cis isomer or a trans isomer—is investigated. While a difference in the catalytic activity of these ...

Two novel oxo-centered trinuclear compounds, [M2M′O(C3H3O2)6(H2O)3] + (M = Cr, M′ = Cr, Fe) have been synthesized. The complexes were characterized by elemental analysis, infrared and electronic spectroscopy and thermogravimetric analysis (TGA). These complexes contain unsaturated carboxylate bridging ligands that cause them to have potential scopes for polymerization in the solid state by cros...

Herein we report the molecular structures and electronic properties of ionic, hydrophobic, half-sandwich complexes of the formula [η(5)-Cp*Rh(L)(MeOH)] (1) and [η(6)-CyRu(L)(H2O)] (2), where L is azo-dye compound of (p-(2-hydroxy-1-naphthylazo)benzenesulfonic acid sodium salt). Both these complexes have been investigated electrochemically and found to display good electronic properties for use ...

Cucurbit[10]uril (CB[10]) is found to form stable host-guest complexes with tetracationic cyclophanes in H2O and DMSO. Upon encapsulation CB[10], the affinity of towards anions weakened, due electronegative carbonyl oxygens on CB[10] providing charge repulsion environment, fixing conformation cyclophanes. Interestingly, these show positively cooperative effects neutral phenol guests heteroterna...

Bivalent metal complexes having the composition M(Phen)Cl2 (where, M = Cu(II), Ni(II) and Co(II); Phen 1,10-Phenonthroline) are reacted with 2-acetylthiophene-4-phenyl-3-thiosemicarbazone (ATPT) to produce ternary molecular formula [M(Phen)(ATPT)Cl2] H2O. The characterized using physical (molar conductivity) spectral (mass spectra, infrared electronic spectroscopies) methods. Electrochemical be...

Metal complexes with pyridine ligands (py) have not been crystallographically characterized in large numbers, while a number of 2,2′-bipyridine (bpy) structurally characterized. Against this background scarcity py complexes, the aim study was to characterize structures and magnetic properties ligands. In study, new trans-[Ni(H2O)2(py)4][BPh4]2·4py (1) trans-[Co(H2O)2(py)4][BPh4]2·4py (2), were ...
