Monohydrate water interaction geometries with model compound M1. Interactions (a) and (b) have the M1 C6-O61 and C5-C6 bonds collinear with the water HO bond, respectively, and with the water molecule in the same plane as the carboxyl group; interactions (c) and (d) have the water HO bond collinear with the ether C1-O5-C5 angle bisector and with the water molecule in the same plane as the C1-O5-C5 atoms; and interactions (e) and (f) have the water molecule forming a tetrahedral interaction with the ether and with the water molecule perpendicular to the plane of the C1-O5-C5 atoms. All molecular graphics were prepared with VMD155.
