Preparation of a Copper(I) Halide Coordination Polymer by Thermal Decomposition of a Precursor with Predefined Stoichiometry

Abstract

The ligand-rich precursor compound tetra-μ-chloro-bis (μ2-2,3-dimethylpyrazine)-tetrakis-(acetonitrile-N)tetracopper(I) (1) was prepared by the reaction of CuCl with 2,3-dimethylpyrazine in acetonitrile. On heating this compound decomposes quantitatively in a single step directly to the ligand-deficient coordination polymer di-μ3-chloro-(μ2-2,3-dimethylpyrazine-N,N′)copper(I).
