An invariom refinement, a structural refinement using aspherical scattering factors from theoretically predicted multipole population parameters, yields accurate geometry and anisotropic displacement parameters, including hydrogen-bonding parameters. All potential hydrogen-bond donors and acceptors are involved in hydrogen bonding, forming an intricate three-dimensional network of N—H O and O—H O bonds %U http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/6772 %~ FID GEO-LEO e-docs
