Název v původním jazyce

Synthesis, crystal structure, thermal and luminescence properties of CuX(2,3-dimethylpyrazine) (X = Cl, Br, I) coordination polymers

Popis výsledku v původním jazyce

Three new coordination polymers based on CuI and 2,3-dimethylpyrazine (2,3-dmpyz) were prepared,structurally characterized and investigated for their thermal and luminescence properties. In the ligand rich 2 : 3 compound [(CuI)2(2,3-dmpyz)3] 1 (CuI)2 dimers are found, which are connected by the N-donor ligands into chains, whereas in the structure of the 1 : 1 intermediate [(CuI)(2,3-dmpyz)] 2 (CuI)4 tetramers are found, which are also connected into chains. The crystal structure of the ligand deficient2 : 1 compound [(CuI)2(2,3-dmpyz)] 3 is built up of CuI double chains, which are connected by the 2,3-dmpyz ligands into layers. Thermal decomposition of 1 results in its direct transformation into the ligand deficient compound 3, without the formationof the 1 : 1 compound 2 as an intermediate. A similar thermal reactivity is found for compound 2, which transforms into 3 on heating.
