TLDR
In this paper, the authors examined the extraction of copper(II) with capric acid from ammonium chloride solutions and determined the composition of the complex extracted and found that the extraction process can be adequately described by the equation: 2Cu (a) 2+ + 3(HR) 2,(0) ⇌ (CuR 2 ·HR)2,( 0) + 4H(a) +About:

Thermodynamic and Steady-State Fluorescence Emission Studies on Metal Complexes of Receptors Containing Benzene Subunits.
Bernardo Ma,Fernando Pina,Enrique García-España,Latorre J,S. V. Luis,Llinares Jm,Ramírez Ja,Concepción Soriano +7 more
TL;DR: Steady-state fluorescence emission studies performed on the Cu (2+) and Zn(2+) complexes show that, while none of the Cu( 2+) complexes is emissive (CHEQ effect), fluorescence emitted is observed for those Zn (2%) complexes with all the nitrogen donors either protonated or coordinated to the metal ions (CHEF effect).

Copper(II) Complexes with Subnormal Magnetic Moments
TL;DR: In this paper, a review of subnormal magnetic moments of copper(II) compounds with subnormal magnet moments can be found, which can be roughly divided into two types: those with direct copper-to-copper interaction and those with super-exchange interaction.
