چکیده
The title compound, C(30)H(26)O(4), is a dimer of 6,6'-dimethyl-dibenzo[d,f][1,3]dioxepine linked by formation of a C-C bond in the para position with respect to one O atom. The dimer is arranged around an inversion centre. As is usually observed in related compounds, the dibenzo group is twisted, the two benzene rings making a dihedral angle of 41.56 (9)°. The seven-membered ring exhibits a twisted conformation.

In the title compound, [CuZnCl(2)(C(19)H(20)N(2)O(4))], the Cu(II) ion exhibits a slightly distorted square-planar coordination geometry defined by two N atoms and two O atoms of the 6,6'-dimeth-oxy-2,2'-[propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolate Schiff base ligand. The Zn(II) ion is also four-coordinated by the two phenolate O atoms of the Schiff base ligand and by two cis-coordina...
