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

Two independent mol­ecules comprise the asymmetric unit in the title benzoxatellurole compound, C12H17ClOTe. The mol­ecules, with the same chirality at the methine C atom, are connected into a loosely associated dimer by Te⋯O inter­actions, 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. Inter­estingly, the TeIV atoms exhibit opposite chirality. The major difference between the independent mol­ecules relates to the conformation of the five-membered chelate rings, which is an envelope with the O atom being the flap, in one mol­ecule and is twisted about the O—C(methine) bond in the other. No directional inter­molecular inter­actions are noted in the mol­ecular packing beyond the aforementioned Te⋯O secondary bonding. The analysis of the Hirshfeld surface reveals the dominance of H⋯H contacts, i.e. contributing about 70% to the overall surface, and clearly differentiates the immediate crystalline environments of the two independent mol­ecules in terms of both H⋯H and H⋯Cl/Cl⋯H contacts.
