1,3-Bis{(+)-(S)-[1-(1-naphth-yl)eth-yl]imino-meth-yl}benzene dichloro-methane solvate
Abstract:
In the title compound, C(32)H(28)N(2)·CH(2)Cl(2), the complete Schiff base and solvent molecules are both generated by crystallographic twofold axes, with the two C atoms of the former and the C atom of the latter lying on the rotation axis. The central benzene ring is substituted with two chiral groups including imine functionalities, with the common E configuration. The dihedral angle between the central benzene ring and the terminal naphthalene ring is 45.42 (9)° and that between the two naphthalene rings is 89.16 (8)°. The conformation of the Schiff base allows solvent mol-ecules to fill the voids in the crystal, affording a stable 1:1 solvate, but the solvent inter-acts poorly with the Schiff base, as reflected by its rather high displacement parameters.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
