Complexes of RuIII, RuII, RhIII, PdIV, IrIII and PtIV with 1,3,4-thiadiazole- 2,5-dithiol have been prepared. Probable structures for the complexes have been proposed on the basis of chemical analyses, magnetic susceptibility and electronic and infrared spectral data. Crystal field parameters have been calculated which are in accordance with the structures proposed. In every complex the ligand behaves as a unidentate towards two metal ions.

Substituted Pyridines

A series of six-coordinated Ni(II) complexes, with the general formula Ni(Xan)L2 (where Xan = isoamyldithiocarbonato and L = 2-bromopyridine, 3-bromopyridine, 4-acetylpyridine, 3-hydroxypyridine and 2-methoxypyridine) are synthesized and characterized by the elemental analysis and various physicochemical techniques such as magnetic susceptibility and conductivity measurements, UV-visible and infrared spectral data. Based on the electronic spectra and magnetic susceptibility measurements, an octahedral geometry is proposed for all the complexes. IR spectral data show that in all these complexes substituted pyridines coordinate to the metal ion through nitrogen atoms occupying the fifth and sixth axial positions, whereas O-alkyldithiocarbonate acts as a monoanion bidentate ligand and occupies the planar positions of octahedral structures. The structure of the adduct with 3-bromopyridine is elucidated by the single crystal X-ray diffraction method. The complex crystallizes in the triclinic space group P-1 with unit cell parameters a = 6.5855(4) Å, b = 9.4984(6) Å, c = 12.4518(8) Å, α = 87.944(5)°, β = 78.843(5)°, γ = 77.794(5)°. The crystal structure of the molecule is stabilized by intermolecular C—H…S and C—H…π interactions.

Complexes of 2-mercaptopyrimidin-4-ol with RhIII, PdII, PdIV, PtII and PtIV have been prepared. Their tentative structures have been assigned on the basis of infrared and electronic spectra and magnetic and analytical data. The ligand behaves as a bidentate bridging ligand towards metal ions except for PtII. Crystal field parameters have also been calculated.

Intuitive Interpretation

AbstractExpanding the crystal field in terms of operators that transform as the irreducible representations of the Td group leads to an intuitive interpretation of the crystal-field parameters. We apply this method to the crystal field experienced by Nd3+ dopants in the laser crystals YLiF4, YVO4, and KLiYF5.
