Abstract

In the absence of stronger hydrogen bonding functionalities, the P [double bond, length as m-dash] O oxygen atom of a variety of related phosphonates forms CH⋯O hydrogen bonds with aryl CH groups and CH functions adjacent to electronegative atoms. In the case of one such compound the interaction results in the propagation of the chirality at phosphorus to form a solid-state right-handed helix with a pitch of 52.675 Å.
