[Cu_2Br_2(BPP)]_n (BPP=l,3-bis(4-pyridyl)propane):A luminescent 2-D inorganic-organic hybrid coordination network with 1-D copper (I) chains bridged by trans-Br atoms

摘要

A new photoluminescent open-framework copper (I) bromide polymer,[Cu_2Br_2(BPP)]_n(BPP = l,3-bis(4-pyridyl)propane) (1),has been hydrothermally synthesized and structurally characterized.The structure of complex 1 features a 2-D inorganic-organic hybrid coordination network with a 1-D copper (I) chain (Cu(I)...Cu(I) separation is 2.849(4) A) bridged by trans-Br atoms.An intense emission of complex 1 at 486 nm (gamma_(ex) = 370 nm) was observed.
