In 3',4'-dihydro-2',2,4,5-tetraphenylspiro[pyrazolidine-3,3'-(2H-1-benzopyran)]-4'-one, the pyrazolidine ring adopts an envelope conformation and the six-membered ring in the flavanone moiety adopts a sofa conformation. The spiro substitution of the pyrazolidine ring causes elongation of the bonds within the flavanone moiety.
