The title compound, C 25 H 26 N 2 Te, was synthesized from bis[1,3-bis(3-phenylpropyl)benzimidazolidin-2-ylidene] and Te in a toluene solution. The molecule possesses a twofold rotation axis passing through the Te atom and the center of the benzimidazole ring system. The benzimidazole ring system makes an angle of 67.9 (4)  with the phenyl rings. Related literature For related literature, see: Akkurt et al. (2004a,b, 2005); Aydın et al.
