Crystal structure of methyl 5-bromo-2-oxo-Δ2-1,3,4-oxadiazolin-3-carboxylate
Abstract
An X-ray crystal structure determination of the title compound has confirmed the cyclic structure and has demonstrated a strong charge-transfer interaction between the carbonyl oxygen and the bromine atoms of adjacent molecules; the medium-dependent i.r. spectra of this molecule are discussed in the light of this finding.
