Abstract

In the title compound, C18H17N3O3, the dihedral angle between the planes of the indazole ring system [maximum deviation = 0.012 (1) Å] and the pyran-2,4-dione ring is 54.03 (6)°. An intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. The same H atom also participates in an inter-molecular N-H⋯O hydrogen bond, which generates an inversion dimer. The dimers are linked by weak C-H⋯O contacts, thereby forming a three-dimensional network.

3-{1-[(1-烯丙基- 1h -茚唑-6-基)氨基]-乙基二烯}-6-甲基- 2h -吡喃-2,4(3H)-二酮的晶体结构。

在标题化合物C18H17N3O3中，茚唑环体系与吡喃-2,4-二酮环的平面之间的二面角[最大偏差= 0.012 (1)Å]为54.03(6)°。分子内的N-H⋯O氢键闭合S(6)环。相同的H原子还参与分子间的N-H⋯O氢键，从而产生反转二聚体。二聚体通过弱C-H⋯O接触连接，从而形成三维网络。

期刊介绍： Acta Crystallographica Section E: Structure Reports Online is the IUCr highly popular open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal structure determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indicators and validation reports provide measures of structural reliability. In 2009, the journal published over 4000 structures. The average publication time is less than one month.
