Cryptands and their Li+ complexes


Conformational analysis of cryptands and Li+ cryptates:
[1.1.1] and [Li+⊂ 1.1.1]
thia-[1.1.1] and thia-[Li+⊂ 1.1.1]
[2.1.0] and [Li+⊂ 2.1.0]
[2.1.1] and [Li+⊂ 2.1.1]

Calculated (DFT) energy of formation of the cryptates*
[1.1.1] -116.2 kcal/mole
thia-[1.1.1]   -102.6 kcal/mole
[2.1.0] -113.8 kcal/mole
[2.1.1] -127.8 kcal/mole
*energy difference between [the most stable conformer of Li+ cryptate] and [the most stable conformer of cryptand plus naked Li+]
