Es. Lavender et al., 2,2 '-Biphenol-1,10-phenanthroline (1/1): A two-dimensional structure built up from three types of hydrogen bond and pi-pi stacking interactions, ACT CRYST C, 55, 1999, pp. 751-754
In the title compound, C12H10O2.C12H8N2, there is an intramolecular O-H...O
hydrogen bond within the 2,2'-biphenol component which is linked to the 1,
10-phenanthroline component via a three-centre hydrogen bond involving both
N atoms as accepters. The bimolecular aggregates are linked by C-H...O hyd
rogen bonds into spiral chains along [010], and these, in turn, are linked
into a sheet parallel to (101) by pi-pi stacking interactions between pairs
of 1,10-phenanthroline units related by centres of inversion.
