摘要
The crystal structure of a pure sample of 9-(3-methylbut-2-enyloxy)-7H-furo[3,2-g]chromen-7-one or imperatorin, C16H14O4, is composed of two independent molecules with different conformations of the 3-methylbutyl group. The structure of an impure sample of imperatorin has already been reported [Cox, Jaspars, Kumarasamy, Nahar, Sarker & Shoeb (2003). Acta Cryst. C59, o520-o522.].
