Synthesis and Crystal Structure of Tetrakis(2-ethylimidazole)bis(thiocyanate-N)nickel(II) Complex

b* , a , b Abstract The title complex, Ni(L)4(NCS)2 (1) (L = 2-ethylimidazole), has been synthesized and charac- terized by X-ray single crystallography. The complex 1 crystallizes in the tetragonal system, P4nc space group with a= 10.587(2), c= 12.927(3) Å, V = 1448.9(4) Å3, Z= 2, R1 = 0.0581 and ωR2 = 0.1675 for 676 independent reflections. The central Ni(II) atom of this complex has a regular octa- hedral coordination geometry, with the 2-ethylimidazole ligands bonding through nitrogen atom and the isothiocyanate ligands bonding through nitrogen atom in a trans arrangement.
