Getting the Big Ones to Pack: Crystal Structure of Vitamin K 2 With a Chaperone

ABSTRACT Packing into a crystal lattice is not easy for flexible molecules with an irregular shape, as all molecules have to adopt the same conformation in order to fit into the same position of a well‐ordered lattice. When numerous conformations are populated at the crystallizat...

Polymorphism and NIR Photoluminescence of Anhydrous Ytterbium(III) Acetate: Reversible Transformations of Three Polar Structures in the Temperature Range 100–593 K

Anhydrous ytterbium(III) acetate Yb(OAc) 3 was obtained by the solvothermal reaction between Yb(OH) 3 and glacial acetic acid in MeOH and subjected to a comprehensive structural investigation in the temperature range 100–573 K. This study revealed a new polymorphic low‐temperatur...
