Bis(perchlorato-κO)tetra-kis[1-(2-pyridyl)-4-(4-pyridylmethyl-κN)piperazine]cadmium(II).

In the title compound, [Cd(ClO(4))(2)(C(15)H(18)N(4))(4)], the Cd(II) ion is coordinated in a slightly distorted octa-hedral environment by two trans monodentate perchlorate ligands and four 1-(2-pyrid-yl)-4-(4-pyridylmeth-yl)piperazine (pmpp) ligands. In the crystal structure, mol-ecules are organized into layers parallel to the ab plane by C-H⋯O inter-actions. Similar inter-actions promote the stacking of these layers into the three-dimensional crystal structure.
