formation constant

https://doi.org/10.1351/goldbook.F02485
For a mononuclear binary complex, if a central atom (central group) M (the 'metal') and a ligand L have been defined, then in the following expressions Kn is the stepwise formation constant, and βn is the cumulative formation constant for the complex MLn. They can both be referred to as stability constants (stepwise and cumulative). Kn=K(MLn−1+L⇌MLn) βn=K(M+nL⇌MLn)
