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 π-π contacts between isoxazole and benzene rings [centroid-centroid distance = 3.969 (3) Å] may further stabilize the structure.
在标题化合物C(16)H(12)N(2)O(4)的分子中,吡啶环相对于呋喃环和异恶唑环以相同的2.92 (3)°二面角取向,而呋喃环和异恶唑环之间的二面角为1.34 (3)°。苯环和吡啶环之间的二面角为53.23 (3)°。在晶体结构中,分子间的C-H⋯O相互作用将分子连接成链。异恶唑环和苯环之间的弱π-π接触[质心-质心距离 = 3.969 (3) Å]可能进一步稳定该结构。
