1-Butyl-1-chloro-3-methyl-3H-2,1λ⁴-benzoxa-tellurole: crystal structure and Hirshfeld analysis.

ABSTRACT: Two independent mol-ecules comprise the asymmetric unit in the title benzoxatellurole compound, C₁₂H₁₇ClOTe. The mol-ecules, with the same chirality at the methine C atom, are connected into a loosely associated dimer by Te⋯O inter-actions, leading to a {⋯Te-O}₂ core. The resultant C₂ClO₂ donor set approximates a square pyramid with the lone pair of electrons projected to occupy a position trans to the n-butyl substituent. Inter-estingly, the Te^IV atoms exhibit opposite chirality. The major difference between the independent mol-ecules relates to the conformation of the five-membered chelate rings, which is an envelope with the O atom being the flap, in one mol-ecule and is twisted about the O-C(methine) bond i
