- Complex method for analysis of hierarchical crystal structure.
- Effect of O-H⋯O hydrogen bonding patterns on the boronic moiety twist.
- Formyl group vs. boronic moiety as an acceptor in O-H⋯O hydrogen bonds.
- H-bond energy estimation for elucidation of 0-D, 1-D or 2-D basic motives.
- Role of H-bonds and π⋯π interactions in formation of 1-D and 2-D large synthons.
