Complexes of 1,2,4-Triazoles, Part XVII The Crystal Structure of Tris-μ-(4-ethyl-1,2,4-triazole-N 1 ,N 2 )- (4-ethyl-1,2,4-triazole-N 1 )-aquo-bis [bis(thiocyanato-N)- nickel(II)]hydrate, Ni 2 (C 4 N 3 H 7 ) 4 (H 2 O)(NCS) 4 ·H 2 O(x ≃ 2.5)
Abstract The crystal structure of Ni 2 (C 4 N 3 H 7 ) 4 (H 2 O)(NCS) 4 · 2.5 H 2 O has been determined by X-ray diffraction techniques. The compound crystallizes in the monoclinic space group P2 1 /n with a = 15.121(4), b= 13.237(2), c= 18.069(3), β = 94.71(2)° and Z = 4; R = 0.040 (Rm = 0.051). The...

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. |
