Abstract: Isomer I of Ni(NCS)₂Q₂.2H₂O (Q = quinoline) was prepd. by dissolving 0.04 moles of NiCl₂.6H₂O in 80 ml. of EtOH and adding to the soln. 0.08 moles of KNCS. KCl was sepd. by filtering and 10 ml. of quinoline was added. Dark green rod-shaped crystals of isomer I formed in the same soln. Also isomer I changed to isomer II after trituration and standing in air at 20° for 7-10 days. Diffusion reflectance spectra show that both complexes have a 6-coordinate pseudooctahedral structure. The ir spectra suggest that the compn. of isomer I is [Ni(NCS)₂. (H₂O)₂Q₂] and that of isomer II is [Ni(NCS)₂Q₂].2H₂O.
