【 摘 要 】

The title compound, [Cu2I2(C11H22N2)2], crystallizes as a symmetric dimer with one quarter of the molecule in the asymmetric unit. The copper(I) atom, the iodine atom and the central methylene C atom of the di(piperidin-1-yl)methane ligand lie on a mirror plane and the complete molecule exhibits point group symmetry 2/m. To the best of our knowledge it is the first diamine copper(I) complex containing a four-membered chelate ring. Compared to other diamine copper(I) iodide dimers, the title compound has a short Cu...Cu distance of 2.5137 (11) Å, but a long Cu—N bond length of 2.213 (3) Å. The I—Cu—I angle [121.84 (2)°] is large, and the N—Cu—N angle = 66.61 (13)° is the smallest one found for copper(I) diamine complexes. As a result of the four-membered ring, the ligands around the copper(I) atom have an extremely distorted tetrahedral arrangement. In the crystal, there are no significant intermolecular interactions present.
