The structures of two alkyne-hexacarbonyl-dicobalt complexes are reported, each with potential ATRP initiator substrates as substituents on the alkynes. The complexes each form tetrahedral C2Co2 cluster cores with classical sawhorse conformations, while a feature of the crystal packing is the formation of inversion dimers for both molecules.

The structure of a hydroacridine with significant pharmaceutical potential is reported. The acridinone ring system is in the shape of a shallow V with the majority of the ring system substituents on its convex surface; a plethora of classical and non-classical hydrogen bonds stack the molecules into interconnected columns.

The structure of a TEMPO derivative with a propynyloxy substituent at the 4-position of the piperidine ring is reported. The crystal packing features an unusual C—Hπ interaction involving the triple bond of the propyne group which combines with C—HO hydrogen bonds to stack the molecules along the b-axis direction.

Packing in the title keto ester compound is dominated by the formation of inversion dimers by both non-classical hydrogen bonds and offset π–π stacking interactions.
