چکیده
There are two independent mol-ecules in the asymmetric unit of the title compound, C16H17NO4, with similar conformations but some differences in their bond angles. Each mol-ecule adopts a trans configuration with respect to the methyl-idene C=N bond and is twisted with a dihedral angle between the two substituted benzene rings of 80.52 (7)° in one mol-ecule and 83.53 (7)° in the other. All meth-oxy groups are approximately coplanar with the attached benzene rings, with Cmeth-yl-O-C-C torsion angles ranging from -6.7 (2) to 5.07 (19)°. In the crystal, independent mol-ecules are linked together by O-H⋯N and O-H⋯O hydrogen bonds and a π-π inter-action [centroid-centroid distance of 3.6030 (9) Å], forming a dimer. The dimers are further linked by weak C-H⋯O inter-actions and another π-π inter-action [centroid-centroid distance of 3.9452 (9) Å] into layers lying parallel to the ab plane.

The aromatic rings of the N,N'-dioxide molecule in the title compound, C(8)H(4)NI(3)O(4)·C(10)H(8)N(2)O(2)·H(2)O, are twisted by 14.0 (2)°. The -CO(2)H substituents of the 5-amino-2,4,6-triiodo-isophthalic acid are twisted by 83.0 (2) and 86.5 (2)° out of the plane of the aromatic ring. In the crystal, the three components are linked by O-H⋯O hydrogen bonds into a three-dimensional network. An ...

The title compound, C15H24N2O2S, was synthesized via a substitution reaction between the enanti-opure (1S,2S)-(+)-1,2-di-amino-cyclo-hexane and 2,4,6-tri-methyl-benzene-1-sulfonyl chloride. The cyclo-hexyl and phenyl substituents are oriented gauche around the sulfonamide S-N bond. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains propagating along [100].

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.
