Oriented crystal fibers of pentacene were produced by a simple casting process from trichlorobenzene solution at elevated temperature. The solution was placed in the air gap between a glass roller and a glass substrate. The width of the air gap was determined by a Teflon spacer wound around both ends of the roller. The roller was moved over the substrate with a constant speed and crystal fibers with approx. 100 nm height, micrometer width and a length of up to 100 µm were formed in the rolling direction. The fibers were characterized by optical microscopy and scanning electron microscopy.

2-Mercapto­thia­zolate is generally used as a monodentate and bridging ligand. We report here the crystal structure of a new type of nickel(II) complex in which the 2-mercapto­thia­zolate ligand acts as a chelating and non-bridging ligand.
