TL;DR: In this article, the binding modes of ionic, unidentate-covalent, and bidentate covalent metalligand binding modes are distinguished in solution by 31P n.m.r.

TL;DR: In this article, the synthesis and characteristics of copper(III) and silver (III) complexes of tellurates and periodates are described, and chemical analysis, I.R. spectra and conductimetric measurements are used to determine the formulae of these anionic complexes.

TL;DR: In this paper, a simple reliable method has been developed for producing solutions of [Ru(dipy)(py) 4 ] 2+ (Dipy = 2,2′-dipyridyl; py = pyridine).

TL;DR: In this article, the authors formulated the triple-bonded complexes as metal-metal triple bonded complexes, which can be generated from the corresponding (η5-C5H5)M(CO)3]2 and (γ-5C(in5)(CH3)5m(CO)-2]2 complexes by either irradiation at 25° or by heating.

TL;DR: In this paper, the Gibbs free energies of transfer based on the bisbiphenylchromium assumption were compared with data obtained from the tetraphenylarsonium tetrahenylborate assumption in those solvents for which such data are available.

TL;DR: In this article, an extension of the angular overlap method was proposed to fit the d-d spectra of chlorocuprates to four freely-chosen parameters, and the theory explains the apparently anomalous spectrum of square coplanar CuCl2−4, and gives a satisfactory account of distant ligands in tetragonal octahedral CuCl6 chromophores.

TL;DR: In this paper, copper(II) complexes of the type CuL 2 X 2 (where L = BTSC and FBTS and X = Cl, Br, NO 3 and NCS) have been prepared with 4-benzylami-dothiosemicarbazide (BTSC) and 1-(α)-furyl-4-benzilamidothio-micarazone (FBTS) and characterized by conventional chemical and physical measurement.

TL;DR: In this paper, the cyclische Natur eines Liganden das Gleichgewicht zwischen den paramagnetischen, blauen Komplexen (I) and den diamagneticalhen, gelben Komplexens (II) beeinflust, wird die Thermodynamik dieser Umlagerung mit Komplexes mit dem Cyclus and den beiden linearen Analogen untersucht.

TL;DR: In this paper, upfield shifts are observed for the acetylenic carbons when L (P- or As-ligand) substitutes one CO 2 (CO) 6 (RC 2 R′) in terms of metal-alkyne bonding.

TL;DR: In this article, the reactions of CH 3 CH 2 C(CH 2 NH 2 ) 3 (tamp) with H +, Ni 2+, Cu 2+ and Zn 2+ were investigated at 298 K in aqueous solution (0.5 M KNO 3 ) using potentiometric techniques.

TL;DR: In this paper, the PMR, EPR and absorption spectroscopy methods have been used to propose the structure of Ni(II) and Cu(II), and the binding sites in tetrapeptide to both metal ions are shown to be the NH2-Thr and three deprotonated nitrogens of peptide linkages.

TL;DR: In this article, the reactions of Thiamine·HCl (ThH), TMP and TPP have been studied in aqueous solutions (pH ∼3-4) at room temperature.

TL;DR: In this article, the synthesis and properties of complexes of the type [Pt(diamine)(dmso)Cl]Cl containing chelate rings of increasing size are reported (DMso = dimethylsulphoxide; diamine = 1,2-diamminoethane (en), 1,3diaminopropane (tn), and 1,4-diminobutane (bn)).

TL;DR: In this paper, the rate law of CoEDTA 2− by periodate was studied and an intermediate was identified spectrophotometrically, which slowly forms hexadentate CoDA −.

TL;DR: In this paper, the authors show that at low [H + ] (0.10 M), the pathway first order in [Fe(II)] predominates, whereas at high [H+ ] ( 0.80 M ), the term second order in Fe(II) prevails.

TL;DR: The XPS photoelectron spectra of mononuclear and polynuclear gold compounds of general formula AunLmXp (L = unsubstitured and para-substitutedtriphenylphosphine, X = anionic ligand) have been measured as mentioned in this paper.

TL;DR: A number of new solvates containing isoxazole as the ligand are reported, viz. [M(isoxazoles) 6 ](BF 4 ) 2 (M is Mn, Fe, Co, Ni, Zn and Cd) as mentioned in this paper.

TL;DR: In this article, the relative stabilities for the cis-and trans-snX4·2L adducts were estimated and the trends in the isomerization constant as a function of substitutions of the ligand and the halogen were discussed on the basis of tin(IV) orbital overlap.

TL;DR: In this paper, the activation energies for the unique iron atom have been evaluated and shown to be influenced by the nature and the number of the substitents at the cobalt atoms.

TL;DR: In this paper, the dithiols 2,3-dimercapto-1-propanol (British anti-Lewisite) and 1,3dimercaptico-2propanoline (2-DDE) form complexes RHgS∼SHgR (R = Me, Ph) and Hg(SR′)2 (R′ = ME, Et, Pri, But, Ph, CH2CH2OH).

TL;DR: A number of metal salts of pyrazole are reported in this article, where the pyrazolato ion acts as a bidentate, and tetrahedral or square planar surrounded metal ions are found.

TL;DR: In this article, a series of compounds of the type PtEt 2 diphos (diphos = 1,2-diphenylphosphinoethane, dppe; 1,3-diphosphinopropane and dppp) has been prepared.

TL;DR: In this article, a series of complex, trans-PtCl 2 (olefin)(L) (L = a nitrogen or oxygen bonded ligand or Cl −, and olefin- cis -2-butene or a monosubstituted olemin), has been studied by infrared, Raman, UV and 13 C NMR spectroscopy.
