Abstract
The coordination chemistry of a series of 2,6- and 2,3-diarylpyrazines with copper(II) acetate is reported. The 2:2 coordination complexes formed between two 2,6-diarylpyrazines and copper(II) acetate are characterized by X-ray crystallography. The structure (2,6-bis(3′,5′-dimethylphenyl)pyrazine)copper(II) acetate acetonitrile solvate, (C48H52Cu2N4O8) ⋅ (C2H3N) is triclinic, P 1, with a = 7.9685(10), b = 13.1893(16), c = 13.8267(17) A, α = 107.585(3)°, β = 103.921(3)° and γ = 96.759(3)°. The structure of (2-(2′,6′-dimethylphenyl)-6-(3″,5″-dimethylphenyl)pyrazine)copper(II) acetate, C48H52Cu2N4O8, is monoclinic, P21/c, with a = 8.2196(7), b = 12.5174(11), c = 21.7325(19) A and β = 96.201(2)°.
