TL;DR: In this paper, a very pronounced enhancement of Raman intensity was found in polar solvents for a polarized band at about 215 cm−1, which could therefore be assigned to the νs(M-N) mode by 15N enrichment of DAB.

TL;DR: In this article, the interaction of several sulfur derivatives of crown-3, crown-4 and crown-6 was studied by a calorimetric titration procedure, showing that the partial substitution of sulfur for oxygen in the crown-5 and Crown-6 ligands results in little change in the affinity of the ligand for Tl + and Pb 2+, but greatly increased affinity for Ag + and Hg 2+.

TL;DR: In this paper, the structure and molecular configuration of bis[N-(2-aminoethyl)salicylaldiminato] iron(III) chloride monohydrate, Fe(III)(Saen)2Cl·H2O, has been determined by X-ray diffraction techniques.

TL;DR: The crystal structure of tris(1,10-phenthroline)iron(II) iodide dihydrate, Fe(C12N2H8)3I2·2H2O, has been determined from X-ray intensity data collected on a four circle diffractometer as mentioned in this paper.

TL;DR: In this article, the structure of tetragonal Ni(II), Cu(II) and Pd (II) complexes with Tyr-GlyGly and Gly-Leu-Tyr has been established by absorption spectroscopy, NMR and EPR methods.

TL;DR: In this article, the preparations and spectral properties of a range of 9-methyladenine compounds with halides of the series MnZn, and also Cd and Hg(II) were reported.

TL;DR: In this paper, the NH stretching vibration in (Ph2PS)2NH, "imidobis(diphenylphosphine sulphide)” cannot be detected in the i.r. spectrum at room temperature but appears as a very weak band at 3250 cm−1 at -180°C.

TL;DR: In this article, the authors characterized the magnetic and infrared properties of bridged Schiff base complexes with 5,5′-methylene-bis-salicylaldehyde and different diamines forming the base.

TL;DR: In this paper, the photoreaction of 5,6-dimethylene-7-oxabicyclo [2.2.1] hept-2-ene with Fe(CO)5 yields initially the dihapto-tetracarbonyl iron complex (3), which reacts further to give a diHaptotetricarbonyl tricarbionyl complex (C8H8O)Fe2(CO),7 (4), and the molecular structure of 4 has been determined by X-ray crystall

TL;DR: In this article, a carbonyl derivative, Re(PPh 3 )(CO)(NAr)Cl 3 (II) (Ar = p -MeOC 6 H 4 ), has been isolated from the reaction of (Ic) with carbon monoxide.

TL;DR: In this paper, the authors show that in all of there systems interactions between the metal orbitals and the π-orbitals of the ligand rings make the dominant contribution to the metal-ligand bonding.

TL;DR: In this paper, a new ligand, referred to as H 4 aapen, has been prepared; it is the ethylenediamine Schiff base derivative of o -acetoacetylphenol and has one site with two nitrogen and two oxygen atoms (N 2 O 2 ) and a second site with four oxygens being common to both sites.
