dissymmetric , auch: dissymmetrical

The park has a tropical dissymmetric climate.

Because the twist can be left-handed or right-handed, the resulting Möbius aromatics are dissymmetric or chiral.

This term is used in chemistry contexts, e.g., for a chiral molecule lacking an asymmetric carbon atom, but possessing two non-coplanar rings that are each dissymmetric and which cannot easily rotate about the chemical bond connecting them: 2,2'-dimethylbiphenyl is perhaps the simplest example of this case.
