A photoluminescent 3D inorganic–organic hybrid coordination polymer [(CuCN)4(bix)]n with a vase-shaped framework of {Cu(CN)} substructure

A new photoluminescent copper(I) cyanide polymer [(CuCN)4(bix)]n (bix = 1,4-bis(imidazole-l-ylmethyl)benzene) has been hydrothermally synthesized and structurally characterized. The structure of this complex features a vase-shaped 3D network of {Cu(CN)} substructure constructed from the puckered layers containing large 34-membered Cu–CN–Cu rings. The present compound was characterized using IR, Elemental analysis and X-ray single-crystal analysis. The photoluminescent property of the title compound was also investigated.

Graphical abstractThe hydrothermal reaction of CuCN and bix (bix = 1,4-bis(imidazole-l-ylmethyl)benzene) in the presence of 4,5-imidazoledicarboxylic acid and HCl in water leads to formation of the pale yellow crystals. The structure of this complex features a vase-shaped 3D network of {Cu(CN)} substructure constructed from the puckered layers containing large 34-membered Cu–CN–Cu rings.Figure optionsDownload full-size imageDownload as PowerPoint slide
