Molecular precursors of bismuth oxide. Synthesis and structure of [Bi22-OC2H4OMe)4(OC2H4OMe)2]∞, a one-dimensional ribbon-like chain

Abstract
Compounds [Bi(OBut)3]∞ and [Bi22-OC2H4OMe)4(OC2H4OMe)2]∞ have been obtained by metathesis reactions between bismuth halides and the appropriate alkali alkoxides; X-ray structure analysis shows a one-dimensional extended ‘skew’ chain structure based on dimeric asymmetric Bi2(OC2H4OMe)6 units in which the metal displays a pyramidal tetragonal surrounding, with a small number of additional neighbours.
