Bis(μ₂-4-nitro­phenolato)bis­(4-nitro­phenolato)di-μ₃-oxido-octa­phenyltetra­tin chloro­form sesquisolvate [+ solvate]: a tetra­nuclear stannoxane

The crystal structure of the tetra­nuclear stannoxane is reported and its structure discussed.

5-Chloro-2-ferrocenylbenzo[d]oxazole

In 5-chloro-2-ferrocenylbenzo[d]oxazole, the chloro­benzo[d]oxazole and the cyclo­penta­dienyl ring attached to it make a dihedral angle of 11.3 (4)°. The conformation of the ferrocenyl moiety is slightly away from eclipsed.

6-Nitro-1,3-benzoxazole-2(3H)-thione

The most important inter­molecular inter­actions in the title compound are bifurcated N—H⋯(O,O) hydrogen bonds.

1-(Cyclo­heptyl­idene)thio­semicarbazide

The title compound has been synthesized and its X-ray crystallographic structure determined so as to analyse its mol­ecular structure, geometrical parameters and hydrogen bonding.

5,10-Di­hydro­indeno­[2,1-a]indene

The title compound, C₁₆H₁₂, crystallizes with four half mol­ecules in the asymmetric unit, each of which is located on a crystallographic centre of inversion. The mol­ecules are essentially planar. The crystal studied was a non-merohedral twin.
