The results show that the whole dataset exhibits the same monotonic trend hinted at in the previous sections by reactions 18A/18B and 21A/21B, where alkyl zinc precursors tend to condense with CUBE to zincosilicates, but these tend to decompose in the presence of SnMe3Cl to produce ZnCl2 and CUBE. The only anomaly is in the case of uncoordinated ZnEt2, where the first condensation is spontaneous but the second is not unless additional stabilization is provided by at least one ligand -a possible sign of the presence of hyperconjugation effects between Zn and Et, which is therefore energetically expensive to lose. This would also explain the much milder ΔG of condensation from uncoordinated states Et2 to Et1 compared to their counterparts with coordinated THF. Analogously to the case of Al, the Zn-Cl structures show greater affinity towards THF coordination compared to their Zn-Et counterparts. At 0 K, coordination of THF is universally preferred, but with increasing temperature, the states with higher coordination numbers are gradually more disfavored to the point where at 373.15 K even the coordination to the zincosilicate site Zn(OSiH3)2 is in equilibrium.
