RESUMO
In the title compound, [Pd(C(23)H(29)N(2)OS(2))(2)], the Pd(II) atom displays the expected square-planar coordination geometry. However, the trans configuration, which allows the Pd(II) atom to be located on a crystallographic inversion centre, is unusual with respect to the cis arrangement found in analogous Pd complexes comprising similar N,S-chelating ligands.

The title mol-ecule, C(18)H(20)N(2)O(4), is located on a crystallographic centre of symmetry. The meth-oxy groups are coplanar with the benzene ring [interplanar angles of 14.4â (2) and 3.1â (3)°], indicating a conjugation effect.
RESUMO
In the title compound, C(16)H(25)N(3)OS, the thio-semicarbazone group adopts an E configuration with respect to the C=N bond and is almost coplanar with the benzene ring, forming a dihedral angle of 9.3â (1)°. In the crystal packing, the mol-ecules lie along the a axis in an anti-parallel arrangement and are held in place by van der Waals inter-actions. As a consequence, there is relatively low anisotropic thermal motion in the terminal atoms of the n-octyl chain.
