چکیده
In the title compound {systematic name: 4-[4-eth-oxy-carbonyl-5-(3,4-methyl-ene-dioxy-phen-yl)-3-oxocyclo-hex-1-en-1-yl]-3-phenyl-1,2,3-oxadiazol-3-ium-5-olate}, C(24)H(20)N(2)O(7), the cyclo-hexene and dioxole rings adopt envelope conformations. The sydnone ring and the attached phenyl ring form a dihedral angle of 79.0 (1)°. In the mol-ecular structure, a C-H⋯O hydrogen bond generates an S(6) ring and a C-H⋯π inter-action involving the phenyl ring is observed. In the crystal structure, mol-ecules are linked into a ribbon-like structure along the a axis by C-H⋯O hydrogen bonds.

In the title compound, C(22)H(24)O(5), each of the cyclo-hexenone rings adopts a half-chair conformation. The hy-droxy and carbonyl O atoms face each other and are orientated to allow for the formation of the two intra-molecular O-H⋯O hydrogen bonds which are typical of xanthene derivatives. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into layers parallel to the ab...
