Sg. Bott et al., CRYSTAL-STRUCTURES OF 3 SUBSTITUTED PENTACYCLO[5.4.0.0(2,6).0(3,10).0(5,9)]UNDECANES, Journal of chemical crystallography, 28(4), 1998, pp. 251-258
The crystal structures of three compounds formed via ultimate nucleoph
ilic attack of unsaturated hydrocarbon fragments are reported. Geometr
ies of the bis(vinyl)-, mono(vinyl), and bis(ethynyl)-substituted PCU
species are unexceptional. The crystal structures are dictated by the
availability of intermolecular hydrogen bonding.
