In the title compound, C(18)H(14)O(6)S, the coumarin ring system is nearly planar, with a maximum out-of-plane deviation of 0.032 (2) Å. The dihedral angle between the benzene ring and the coumarin ring system is 32.41 (8)°. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions, generating C(8), C(10) and C(11) chains and an R(2) (2)(10) ring. The formyl group is disordered over two sets of sites, with occupancies of 0.548 (5) and 0.452 (5).
在标题化合物C(18)H(14)O(6)S中,香豆素环系近乎平面,最大平面外偏差为0.032 (2) Å。苯环与香豆素环系之间的二面角为32.41 (8)°。晶体堆积通过分子间C-H⋯O相互作用得以稳定,形成C(8)、C(10)和C(11)链以及一个R(2) (2)(10)环。甲酰基在两组位置上无序分布,占有率分别为0.548 (5)和0.452 (5)。
