چکیده
The title compound, C(17)H(26)O, is a di-ortho-alkyl substituted phenyl ethanone that exhibits a significant twisting of the ketone fragment relative to the aromatic ring [O-C-C-C torsion angle = 89.32 (17)°] due to steric pressure from the ortho-isopropyl groups. One ortho- and the para-isopropyl group exhibit orientational disorder with a refined site occupancy factor of 0.562 (3):0.438 (3).

In the mol-ecular structure of the title compound, C(34)H(58)B(2)N(2), each B atom of the diborane(4) is connected to one dimethyl-amino group and one Tip ligand (Tip = 2,4,6-triisopropyl-phen-yl). These findings indicate that the increased steric demand of the Tip groups exerts influence solely on the B-B separation but not on the overall geometry of the title compound.

The title compound, [Sn(2)(C(72)H(98))Te(2)(Te(3))], has a cage-like structure with bulky aryl substituents on the Sn atoms. The mol-ecule sits over a crystallographic twofold axis, and hence the asymmetric unit consists of one half-mol-ecule. Due to the twofold axis, the tritelluride part has a 1:1 disorder. One of the six-membered rings has a boat conformation, whereas the other has a chair c...

In the title compound, C(6)H(6)N(2)O(3)·C(8)H(8)O(4), the 2-amino-4-nitro-phenol (ANP) and 1-(2,4,6-trihy-droxy-phen-yl)ethanone (THA) mol-ecules are both nearly planar, with r.m.s. deviations of 0.0630 and 0.0313 Å, respectively. The angle between the least-squares planes of THA and ANP is 48.99 (2)°. In THA, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, ...

The six-membered oxacyclo-hexene ring of the title compound, C(13)H(14)N(2)O(2)S, is fused with the benzene ring and the quarternary C atom lies above the plane of the benzene ring by 0.229 (8) Å, whereas the methine C atom (which bears the acetyl substituent) lies below this plane by 0.595 (8) Å. The oxacyclo-hexene ring is also fused with the sofa-shaped 2,6-diaza-cyclo-hexa-none ring. The me...
