Figure 2
(a) The ester Osp³ atom as a single acceptor; (b) as a double acceptor; (c) as an acceptor of a proton involved in an intermolecular bifurcated hydrogen bond; (d) as an acceptor of a proton involved in an intermolecular bifurcated hydrogen bond using the carbonyl oxygen atom of the same ester group as an additional acceptor. Geometric parameters are defined for the hydrogen-bond length d ≡ O⋯H and angle α ≡ O—H⋯O.
