Synthesis, crystal structure and thermal properties of di-μ-iodido-bis-[bis-(2-chloro-pyrazine-κN)copper(I)].

ABSTRACT: Reaction of copper(I) iodide in pure 2-chloro-pyrazine leads to the formation of a few crystals of the title compound, [Cu₂I₂(C₄H₃ClN₂)₄] or (CuI)₂(2-chloro-pyrazine)₄, which was characterized by single-crystal X-ray diffraction. In its crystal structure, the Cu^I cations are each tetra-hedrally coordinated by two iodide anions and two 2-chloro-pyrazine ligands and are linked into binuclear complexes consisting of (CuI)₂ rings located on centers of inversion. PXRD investigations of a few crystals obtained from the suspension indicate that the title compound is contaminated with a small amount of the 2-chloro-pyrazine-deficient compound CuI(2-chloro-pyrazine) already reported in the
