Abstract

The mol-ecule of the title chalcone, C(25)H(20)O(2), consisting of 2-eth-oxy-phenyl and anthracene rings bridged by a prop-2-en-1-one unit, is twisted and exists in the Z configuration with respect to the central C=C bond. The dihedral angle between the benzene and anthracene rings is 78.17 (9)°. The propene unit makes dihedral angles of 44.5 (2) and 81.1 (2)° with the benzene and anthracene rings, respectively. The eth-oxy substituent is almost coplanar with the attached benzene ring [C-O-C-C torsion angle = 178.57 (19)°]. In the crystal, mol-ecules are linked into chains along the a axis by weak C-H⋯O inter-actions. The crystal structure is further stabilized by C-H⋯π inter-actions.

摘要

标题查尔酮分子C(25)H(20)O(2)由2-乙氧基苯基和蒽环通过一个1-丙烯-1-酮单元桥连而成，分子呈扭曲状，相对于中心C=C键以Z构型存在。苯环和蒽环之间的二面角为78.17 (9)°。丙烯单元与苯环和蒽环的二面角分别为44.5 (2)°和81.1 (2)°。乙氧基取代基几乎与相连的苯环共面[C-O-C-C扭转角 = 178.57 (19)°]。在晶体中，分子通过弱的C-H⋯O相互作用沿a轴连接成链。晶体结构通过C-H⋯π相互作用进一步稳定。
