Crystal structure of rac-(3aR*,9aS*)-4,4,4-tri-chloro-1,2,3,3a,4,9a-hexa-hydro-4λ(5),9λ(4)-cyclo-penta-[4,5][1,3]tellurazolo[3,2-a]pyridine.

ABSTRACT: The title compound, C10H12Cl3NTe, crystallizes with two crystallographically independent mol-ecules (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 mol-ecules 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 mol-ecules A and B, respectivly] are substan-ti-ally shorter than the third Te-Cl distance [2.8786 (7) and 2.8763 (7) Å in mol-ecules A and B, respectivly]. The 1,3-tellurazole ring is almost planar (r.m
