Crystal structure of 1-hydroxymethyl-4-methyl-7-oxabicyclo[4,3,0]non-4-en-8-one

Abstract

Crystals of the title compound are monoclinic, a= 7·973, b= 6·249, c= 9·444 Å, β= 95·8°, Z= 2, with space group P2₁. The structure was determined from diffractometer data by direct methods, and refined by full-matrix least-squares to R 0·068 for 681 data. The two rings are cis-fused and the molecules are hydrogen-bonded in chains parallel to the a axis. Bond lengths and angles are generally normal.
