The structure exhibits a spatial arrangement with one [HN-(CH 2 ) 3 -O-(CH 2 ) 6 -O-(CH 2 ) 3 -NH] as an arch, grafted in a trans configuration onto two different phosphorus atoms ( trans non-gem disubstitution) of one N 3 P 3 Cl 4 moiety. This fortuitously discovered trans -19-crown-ether-shaped macrocyclic structure defies the well-established description of the electronic structure of six-membered
