N-[6-(Dimethylamino)-9-phenyl-3H-telluroxanthen-3-ylidene]-N-methylmethanaminium hexafluorophosphate monoclinic polymorph

Abstract

The title compound C23H23N2Te+·PF6−, is a monoclinic polymorph of the previously reported triclinic structure [Calitree et al. (2007). Organometallics, 26, 6248–6257]. In the crystal, parallel offset π–π stacking [shortest centroid–centroid separation = 3.9620 (9) Å] and ionic interactions help to establish the packing.
