2-Tosyl-2,3,3a,4,9,9a-hexa­hydro-1H-benzo[f]isoindol-1-one

The title compound, C₁₉H₁₉NO₃S, was produced by the self-reaction of N-cinnamyl-N-tosyl­acryl­amide in the presence of palladium(II) acetate via an intra­molecular C—C coupling reaction and C—H activation. There are two chiral C atoms in the mol­ecule, but the crystal is a racemic system due to a lack of chiral separation. The five-membered ring is twisted about the methyl­ene–methane bond, and the cyclo­hexa-1,4-diene ring has a boat conformation. The dihedral angle between the benzene rings is 88.27 (14)°, indicating an almost orthogonal relationship and an approximate L-shape for the mol­ecule. In the crystal, the presence of C—H...π inter­actions leads to inversion dimers.

Bis(ethyl­eneglycolato-κ²O,O′)tellurium(IV)

The title compound, C₄H₈O₄Te, crystallized from a solution of Te⁴⁺ in ethyl­ene glycol. The Te^IV atom is in a distorted seesaw coordination defined by four O atoms from two different ethyl­eneglycate ligands. The C atoms of the ethyl­eneglycate ligands are disorderd over two positions, with population parameters of 50.3 (6) and 49.7 (6)% indicating a statistical distribution. Due to the possibility to transform the primitive monoclinic unit cell into a metrically ortho­rhom­bic C unit cell, the data are twinned and were refined with the twin law -100/0-10/101 with the relative scale factor refining to 1.82 (4)% for the minor component.
