O hydrogen bonds are observed. O interactions are found in the crystal structure. The water molecules participate in extensive hydrogen bonding and link molecules into a two-dimensional network.
O hydrogen bonds are observed.
All bond lengths and angles show normal values.
O interactions form a hydrogen-bonded network. A twofold rotation axis passes through the bridgehead C atom. O hydrogen bonds, forming a supramolecular assembly. One of the six-membered rings adopts a screw-boat conformation, one adopts an envelope conformation and the third is planar.
