Copper(II) complexes of salicylal-4-amino antipyrine and 2-hydroxy naphthal-4-amino antipyrine
TL;DR: In this paper, the magnetic moments of the perchlorate complexes show metal-metal interaction whereas all other complexes show normal magnetic behaviour, and the electronic spectra of the chloride and the bromide complexes indicate a tetrahedral structure for them, while the other complexes are in favour of a square or distorted octahedral structure.
