1. 2-, simple phosphate monoester or phosphonate ligand with R representing a noncoordinating residue (see also caption for Figure 4); tn, 1,3-diaminopropane (trimethyl-enediamine). Species which are given in the text without a charge either do not carry one or represent the species in general (i.e., independent from their protonation degree); which of the two versions applies is always clear from the context.

46. The calculation procedure (Newton-Gauss nonlinear least-squares fitting) is based on eq 4 given in ref 17b. The six data points seen in Figure 2 were read out from figure 6 (after its enlargement) in ref 21.

57. 2. From this point of view our results represent then actually the difference between phosphate protonated (the concentration of which may be low) and deprotonated forms. To say it differently: We obtain the formation degrees of the outer-sphere macrochelates on top of what is possibly already present in the protonated forms.
58. a values are based on the difference toward the complexes formed with 1,1,4,7,7-pentamethyl-dien and thus there could also be a contribution due to steric inhibition; if so, the given formation degrees would be somewhat too large. However, considering this and especially that these complexes differ significantly from the present one in their composition, one may note that the orders of the formation degrees are still relatively similar.
