Abstract

The reaction of a flexible monothioether ligand, 2-[(o-pyridyl)-sulfanylmethyl]-pyrimidine (L), with CuI leads to the formation of a novel complex [Cu4I4(L)2] (1), which has been characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction analysis: monoclinic, space group P21/n, with a = 10.921(5), b = 10.824(5), c = 13.128(6) Å, β = 109.333(5)° and Z = 2. Single-crystal X-ray analyses show that complex 1 is tetranuclear structure with a distorted chair-like Cu4I4 skeleton. Cu···Cu interactions are found to exist in this tetranuclear molecule. In the packing mode of complex 1, there exist N………I weak interactions and intermolecular π–π contacts. These weak interactions not only stabilize the structure of complex, but also further link the tetranuclear molecules into a high-dimensional supramolecular architecture.
