The largest number of hydrogen bonds in crystal structures of alkyl hydroperoxides refer to intermolecular bonds between the hydroperoxide proton and functionalities of the type 0=X, where X denotes a sulfur (e.g. 27), carbon (e.g. 30) or a phosphorous atom (e.g. 32, Figure 14, Table 7)93,108,115 geometry of [l,2-bis(diphenylphosphinoyl)ethane] bis(2,2-dihydroperoxypropane) (32) in the solid state is a rare example of a bifurcated hydrogen bond between an OOH donor and an 0=X proton acceptor. 

F. 7.4 Left Stmcture of a cylindrical capsule. The peripheral alkyl groups, R = C11H23, are not shown but impart solubility in organic solvents. Center The space available inside the capsule is a tapered cavity with a volume of 425 A. Right A belt of eight bifurcated hydrogen bonds holds the capsule together...
