5,6-Dimethylbenzo[d][1,3]oxatellurole

Abstract

The structure of the title compound, C9H10OTe, at 100 K has orthorhombic (P21212) symmetry with two independent molecules in the asymmetric unit (Z′ = 2). The molecules are folded along their Te...O axes, with their Te–C–O planes angled at an average of 25.1° with respect to the remaining non-H atoms, which are almost coplanar (average deviation from planarity = 0.04 Å). A Hirshfeld plot shows weak intermolecular interactions between the two Te atoms located in each asymmetric molecule, with a Te...Te distance of 3.7191 (4) Å. The structure is strongly pseudosymmetric to the space group Pccn with Z′ = 1. The crystal chosen for data collection was found to be was an inversion twin.
