摘要：

In the first title compound, [Ni(C2H3N)(2)(C11H26H4)](I-3)(2), the Ni-II centre is coordinated octahedrally: all four N-donor atoms of the macrocyclic ligand occupy an equatorial plane and the coordination is completed by two axial acetonitrile ligands. Each N-H group forms a contact of 2.97-3.11 Angstrom to one I atom of an I-3(-) anion. One of these anions participates in long I ... I contacts of 4.008 (3) Angstrom to form infinite chains of symmetry-related anions. In the second title compound, [Pd(C11H26N4)](I-3)(2), each Pd-II centre is coordinated in an equatorial plane by four N-donor atoms from the macrocyclic ligand and axially by a terminal iodine from each of two I-3(-) anions at 3.525 (4) Angstrom. The same I atom forms an I ... I contact of 4.094 (3) Angstrom such that cations and pairs of anions alternate within one-dimensional zigzag chains.
