 Title    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.

 Title    Complexes of 1,2,4-Triazoles, Part XVII The Crystal Structure of Tris-/«-(4-ethyl-l,2,4-triazole-N l ,N 2 )- (4-ethyl-l,2,4-triazole-N 1 )-aquo-bis [bis(thiocyanato-N)- nickel(II)]hydrate, Ni2(C4N3H7)4(H20)(NCS)4 *H20 (x ~ 2.5)  
 Abstract    The crystal structure of Ni2(C4N3H7)4(H20)(NCS)4 • 2.5 H20 has been determined by X-ray diffraction techniques. The compound crystallizes in the monoclinic space group P2i/n with a — 15.121(4), 6= 13.237(2), c= 18.069(3), ß = 94.71(2)° and Z = 4; R = 0.040 (Rm = 0.051). The compound consists of dimeric units in which two Ni ions are bridged by three ethyltriazole (Ettrz) groups. For one Ni, two N donating NCS" groups and an Ettrz coordinating by only one N atom complete the NiNe octahedron. The other Ni atom, which is also octahedrally coordinated, has a coordinated water molecule instead of a monodentate Ettrz.
