The title compound, C10H12Cl3NTe, crystallizes with two crystallographically independent molecules (A and B) in the asymmetric unit. In each case, the coordination around the Te atom is distorted square-pyramidal, with the equatorial plane composed of the three Cl atoms and the C atom of the pyridinium ring. The Te atom is displaced from the mean-square plane by 0.1926 (7) and 0.1981 (8) Å, in molecules A and B, respectivly, away from the apical C atom. The bond lengths from the Te atom to the two Cl atoms arranged trans to each other [2.5009 (7)/2.5145 (7) and 2.5184 (7)/2.5220 (8) Å in molecules A and B, respectivly] are substantially shorter than the third Te—Cl distance [2.8786 (7) and 2.8763 (7) Å in molecules A and B, respectivly]. The 1,3-tellurazole ring is almost planar (r.m.s. deviations of 0.042 and 0.045 Å in molecules A and B, respectivly). The cyclopentane rings in both molecules A and B adopt envelope conformations with the carbon atom opposed to the (Te)C—C(N) bond as the flap. In the crystal, molecules form centrosymmetric 2 + 2 associates via Te⋯Cl interactions [3.3993 (7) and 3.2030 (7) Å]. As a result of these secondary interactions, the Te atom attains a strongly distorted 5 + 1 octahedral environment. Further, the 2 + 2 associates are bound by weak C—H⋯Cl hydrogen bonds into a three–dimensional framework.

“…In the last years, the selenium-and nitrogen-containing heterocycles have attracted considerable attention owing to the variety of their pharmacological properties (Mugesh et al, 2001;Wright, 2001;Koketsu & Ishihara, 2003;Nogueira et al, 2004;Bhabak & Mugesh, 2007;Garud et al, 2007;Sommen et al, 2007;Back, 2009;Mlochowski & Giurg, 2009;Mukherjee et al, 2010). This article describes the structure of 8,12b-dihydro-7aH-indeno [1′,2′:5,6] (Borisov et al, 2011) with potassium hydrosulfate (Fig. 1) five-membered ring (cyclopentene) and four six-membered rings (two benzene, 3,6-dihydro-1,4-selenazine and pyridine) (Fig.…”

In the title compound, C18H14NSe+·HSO4 −, the cyclopentene ring in the cation has an envelope conformation while the central six-membered 1,4-selenazine ring adopts a sofa conformation. The dihedral angle between the planes of the terminal benzene rings is 68.08 (11)°. In the crystal, the anions form chains along the c axis through O—H⋯O hydrogen bonds. Weak C—H⋯O and C—H⋯π hydrogen bonds, as well as attractive Se⋯Se [3.5608 (8) Å] interactions, further consolidate the crystal structure.
