Abstract

In the title heteroaryl chalcone derivative, C(16)H(16)O(5), the dihedral angle between the furan and benzene rings is 14.45 (6)°. The three meth-oxy groups are almost coplanar with their attached benzene ring [C-C-O-C torsion angles = 2.07 (17), -5.04 (17) and 2.85 (16)°]. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, adjacent mol-ecules are linked into X-shaped chains along the c axis by weak C-H⋯O(enone) inter-actions. These chains are stacked along the b axis. C⋯O [3.3308 (13)-3.4123 (14) Å] short contacts are also observed.

摘要

在标题杂芳基查尔酮衍生物C(16)H(16)O(5)中，呋喃环和苯环之间的二面角为14.45 (6)°。三个甲氧基与其相连的苯环几乎共面[C-C-O-C扭转角 = 2.07 (17)、-5.04 (17) 和2.85 (16)°]。存在分子内C-H⋯O氢键。在晶体中，相邻分子通过弱C-H⋯O（烯酮）相互作用沿c轴连接成X形链。这些链沿b轴堆积。还观察到C⋯O [3.3308 (13)-3.4123 (14) Å] 短接触。
