The monoclinic polymorph of rac-5,7,7,12,12,14-hexamethyl-1,4,8,11-tetraazoniacyclo-tetradecane bis(hexafluorogermanate) tetrahydrate

Studies on inclusion compounds. The ability of crown ethers to stabilize in the form of proper host-guest complexes normally unstable or volatile was still analyzed by structural studies of the title polymorph in which the water moleculs and the [GeF6]-2 anions form zigzag chains which alternate in a three dimnsional network with macrocyclic cations. The system is sustained by multiple hydrogen bonds.
