Spectroscopic evidence for the conversion of octahedral nickel(II) into tetrahedral nickel(II)

Abstract

Spectroscopic evidence suggests that the complexes of 8-amino-2-methylquinoline (maq) with nickel(II) of the type, Ni(maq)₂X₂,nH₂O (X = Cl, Br, I, NO₃, and CIO₄), Ni(maq)₂XClO₄(X = Cl, I, and NO₃), and Ni(maq)X₂,nH₂O (X = Cl, Br, and I) give rise to tetrahedral species when set aside in methanol.
