Abstract
Crystals of the title compound are orthorhombic, a= 7·265(2), b= 7·325(2), c= 13·286(5)Å, Z= 4, space group Pnma. The structure was determined from X-ray counter data and refined by full-matrix least-squares calculations to R 0·040 for 527 observed reflections. The six-co-ordinate indium lies on a mirror plane and is bonded to two approximately trans-methyl groups, which also lie in the mirror plane, and four oxygen atoms. A bidentate acetate group lies across the mirror plane, with In–O 2·371 (5)Å, while two weaker bridging contacts from different adjacent acetate groups with In–O 2·600(5)Å, serve to link the structure as a linear polymer. These bond length differences are unexpected since in a compound of this type the bridge bonds would be expected to be shorter than those of the bidentate acetate.Keywords
