Abstract
2-Methoxi-1,3,2-benzodioxastibole is prepared by transesterification of (CH3O)3Sb with catechol. Recrystallization from m ethanol yields colourless crystals, the structure of which was solved and refined to a conventional R-value of 0.04 with 915 reflections observed. The space group is P 21/n with 4 molecules in the unit cell. Interaction with oxygen atoms of two neighbouring molecules enlarges the coordination number on the antimony to five, thus forming a structure with infinite chains along the α-axis.Keywords
