Abstract

A novel mixed-valence CuI/CuII coordination polymer [CuI(μ2-Cl)CuII(μ3-S)(Phen)]n (I) (Phen = 1,10-phenanthroline) has been hydrothermally synthesized and structurally characterized by elemental analyses and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis reveals that a unique one-dimensional infinite chain-like structure is constructed by two unusual zigzag chains of [CuCl]n and [CuS]n. Both of the zigzag chains are used as the second building units (SBU) to produce a 2D helix-like layer at the aid of the C-H...Cl hydrogen bonding interactions between Phen groups and [CuCl]n chains. An interesting three-dimensional network is formed with the supramolecular van der Waals contacting among the 2D layers. Finally, the magnetic properties of the title compound have been investigated in the temperature range 2–300 K.
