 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.

 Title    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.
