چکیده
The asymmetric unit of the title compound, C(18)H(22)Br(2)N(2)O(2), contains one half-mol-ecule that is related to the other half by a center of inversion located at the mid-point of the central C-C bond. The hy-droxy (phenolic) groups are linked to the N atoms by O-H⋯N hydrogen bonds, which generate S(6) rings.

The title compound, C21H26Cl2N2O2, was prepared in a solvent-free microwave-assisted synthesis, and crystallizes in the ortho-rhom-bic space group Pna21. The imidazolidine ring adopts an envelope conformation and its mean plane is almost perpendicular to the two pendant aromatic rings [dihedral angles = 84.61 (9) and 86.54 (9)°]. The mol-ecular structure shows the presence of two intra-molecula...

The title complex, [Cu(C(18)H(16)Br(2)N(2)O(4))(H(2)O)], lies on a crystallographic mirror plane with the Cu(II) ion coordinated by two N atoms and two O atoms of a tetra-dentate Schiff base ligand and one O atom from a water ligand in a slightly distorted square-pyramidal environment. The mirror plane, which coincides with the Cu-O(water) bond, imposes disorder of the atoms of the ethyl-ene gr...
