Synthesis and crystal structure of poly[[μ-chlorido-μ-(2,3-di-methyl-pyrazine)-copper(I)] ethanol hemisolvate], which shows a new isomeric CuCl(2,3-di-methyl-pyrazine) network.

ABSTRACT: Reaction of copper(I)chloride with 2,3-di-methyl-pyrazine in ethanol leads to the formation of the title compound, poly[[μ-chlorido-μ-(2,3-di-methyl-pyrazine)-copper(I)] ethanol hemisolvate], {[CuCl(C₆H₈N₂)]·0.5C₂H₅OH} _n or CuCl(2,3-di-methyl-pyrazine) ethanol hemisolvate. Its asymmetric unit consists of two crystallographically independent copper cations, two chloride anions and two 2,3-di-methyl-pyrazine ligands as well as one ethanol solvate mol-ecule in general positions. The ethanol mol-ecule is disordered and was refined using a split model. The methyl H atoms of the 2,3-di-methyl-pyrazine ligands are also disordered and were refined in two orientations rotated by 60° relative to each other. In the crystal struc
