Ternary Cu2+ Complexes: Stability, Structure, and Reactivity
TL;DR: In this article, the driving forces leading to the formation of ternary Cu2+ complexes are outlined; they are (i) statistical reasons, neutralization of charge in the mixed-ligand complexes, steric factors (bulky groups, ring size of chelates), and formation of π bonds.

The IUPAC stability constants database
TL;DR: The first compilation was published in 1957 under the auspices of IUPAC and was followed by further volumes in 1964,1971, and 1983 as discussed by the authors, which included data to about 1973, including most of the major pioneers in the field: G. Schwarzenbach, L. Sillen, G. Anderegg, J. Bjerrum, A. Hogfeldt, E.G.
