TL;DR: In this paper, the room temperature crystal structures of three hydroxy-flavone derivatives have been solved, and the relationships between molecular conformation and solid-state aggregate patterns of 3-hydroxyflavones and related molecules are discussed in terms of possible ground state solute solute-solvent and solvent-solute solution structures.

TL;DR: In this article, the X-ray crystal structures of praseodymium(III) acetate monohydrate and europium (III) trihydrate have been solved and cross-polarization carbon-13 NMR spectra obtained in the polycrystalline solids.
Abstract: The X-ray crystal structures of praseodymium(III) acetate monohydrate and europium(III) acetate trihydrate have been solved and cross-polarization carbon-13 NMR spectra obtained in the polycrystalline solids. The static and magic angle spinning spectra are compared with diamagnetic acetate spectra. The shifts in the paramagnetic compounds are large, permitting sample heterogeniety to be readily detected. THE CP-MASS carbon spectra are assigned by using both relaxation times and dipolar interactions as a guide.
