n-Propyl gallate (PG) is a charge-control agent used for toners in electrophotography, and shows pseudo-polymorphism. The title compound, 3C10H12O5·0.5CH2Cl2, is isostructural with the corresponding chloro­form solvate. The asymmetric unit is composed of three PG mol­ecules and a half-mol­ecule of dichloromethane, the solvent being disordered over an inversion centre. There are intra- and inter­molecular O-H...O hydrogen bonds, forming a two-dimensional hydrogen-bond network in the (421) plane.

Virus crystals can incorporate a wide range of unusual impurities, not possible for conventional crystals or even most protein crystals, because of the large size of their constituent particles. Examples of several of these unusual impurities are presented here, along with some of the consequences for the crystal lattices.

Bence Jones KWR protein, an immunoglobulin light-chain dimer, was crystallized under a variety of conditions after 40 y storage. Structures were obtained with packing arrangements consistent with biochemical and biophysical observations suggestive of an AL-type amyloid-fibril structure. Obtaining molecular-replacement solutions for these crystals proved to be a crystallographic challenge, probably owing to intradomain flexibility and the presence of disordered and proteolytically modified regions.

The title compound, [Zn(C15H21O3)2(C3H6OS)2], is a powerful charge-control agent used widely for toners in electrophotography. This ZnII complex has no molecular symmetry and possesses a deformed tetra­hedral coordination geometry. Two 3,5-di-tert-but­yl-2-hydroxy­benzoate ligands serve as monodentate ligands, while two dimeth­yl sulfoxide mol­ecules are coordinated to the Zn atom.

The title compound, [Zn3(C15H21O3)6(C2H3N)2], has a center of symmetry and contains one six-coordinate Zn atom located at the center of the molecule and two four-coordinate Zn atoms at the periphery. Each 3,5-bis­(1,1-dimethyl­eth­yl)-2-hydroxy­benzoate anion serves as a bridging ligand between the central and peripheral Zn atoms. An acetonitrile mol­ecule is coordinated to each peripheral Zn atom.
