Abstract

In the title compound, C36H28O4, the two 2-naphthoyl groups at the 1- and 8-positions of the central 2,7-dieth-oxy-naphthalene ring system are aligned almost anti-parallel and make a dihedral angle of 48.35 (5)°. The dihedral angles between the central 2,7-dieth-oxy-naphthalene ring system and the terminal naphthalene ring systems are 77.64 (4) and 73.73 (4)°. In the crystal, mol-ecules are linked into chains along the a-axis direction by dual C-H⋯O inter-actions between naphthoyl groups.

摘要

在标题化合物C₃₆H₂₈O₄中，中心2,7 - 二乙氧基萘环体系1位和8位的两个2 - 萘甲酰基几乎反平行排列，二面角为48.35 (5)°。中心2,7 - 二乙氧基萘环体系与末端萘环体系之间的二面角分别为77.64 (4)°和73.73 (4)°。在晶体中，分子通过萘甲酰基之间的双重C—H⋯O相互作用沿a轴方向连接成链。
