Description
| - Reaction of CuBr with an excess of 2,3-dimethylpyrazine in acetonitrile leads to the formation of the literature known ligand-rich 1 : 1 compound poly [mu(2)-bromo-mu(2)-2,3-dimethylpyrazine-N,N'-copper(I)] (1). On heating this compound in a thermobalance a transformation into the new ligand-deficient 2: 1 compound poly [di-mu(3) -bromo-mu(2) -2,3-dimethylpyrazine-N,N'-dicopper(I)] (3) is observed, which later was also prepared in solution. This compound crystallizes in the monoclinic space group P2(1)/n with all atoms in general positions. In the crystal structure the Cu atoms are surrounded by three Br atoms and one 2,3-dimethylpyrazine ligand within a distorted tetrahedron. The tetrahedra are connected via common Br edges into CuBr double chains, which are connected by the ligands into layers located in the ab plane. The formation of compounds 1 and 3 was also investigated in solution. The results have shown that compound 1 can only be prepared if an excess of the ligand is used.
