| Magnetic and Spectroscopic Properties of Metal(II) Thiocyanate Compounds with 3,4-Dialkyl Substituted 1,2,4-TriazoIes  | | | | Abstract
| Syntheses, spectroscopic and magnetic properties are described of a series of metal(II) thio-cyanate compounds with the asymmetric ligands 3-methyl-4-ethyl-l,2,4-triazole and 3-methyl-4-;-butyl-l,2,4-triazole. A dinuclear structure is proposed for the manganese, cobalt and nickel compounds based on the magnetic behaviour as well as on spectroscopic and analytical data. These compounds show antiferromagnetic interaction in the temperature range 4—80 K. The zinc compounds appear to be mononuclear, whereas a chain-like structure is proposed for the cad-mium compounds. | | | |

| Complexes of 1,2,4-Triazoles, Part XVI Binuclear Complexes of Transition Metal(II)thiocyanates with 4-Ethyl-l,2,4-triazole | | | | Abstract
| Coordination compounds of 4-ethyl-l,2,4-triazole (Ettrz) with Mn, Fe, Co, Ni, Cu and Zn are reported. The compounds have been identified and characterized by chemical analyses, infrared and ligand field spectra, electron paramagnetic resonance (e.p.r.) measurements, magnetic susceptibility measurements and thermoanalytical experiments. Except for the Cu compound, which is polynuclear, all compounds appear to be binuclear, with both bridging bidentate and non-bridging triazole ligands. The overall formula is M(Ettrz)2(NCS)2(H20)3/2 for Mn, Fe, Co and Ni. The copper and zinc compounds have the formula Cu(Ettrz)2(NCS)2 and Zn(Ettrz)3/2(NCS)2. | | | |
