4-(4-Methoxy-phen-yl)-3-methyl-1,6-di-oxa-2,8-diaza-s-indacen-5(7H)-one.

ABSTRACT: In the mol-ecule of the title compound, C(16)H(12)N(2)O(4), the pyridine ring is oriented at the same dihedral angle of 2.92?(3)° with respect to the furan and isoxazole rings, while the dihedral angle between furan and isoxazole rings is 1.34?(3)°. The dihedral angle between the benzene and pyridine rings is 53.23?(3)°. In the crystal structure, inter-molecular C-H?O inter-actions link the mol-ecules into chains. Weak ?-? contacts between isoxazole and benzene rings [centroid-centroid distance = 3.969?(3)?Å] may further stabilize the structure.

In the mol-ecule of the title compound, C(16)H(12)N(2)O(4), the pyridine ring is oriented at the same dihedral angle of 2.92 (3)° with respect to the furan and isoxazole rings, while the dihedral angle between furan and isoxazole rings is 1.34 (3)°. The dihedral angle between the benzene and pyridine rings is 53.23 (3)°. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into chains.
