Synthesis, structure and luminescent property of a novel Ag(I) complex: [Cu(pn) 2 ][Ag 3 (CN) 5 ].

Assembly of [Ag(CN) 2 ] - units with diaminecopper(II) cation [Cu(pn) 2 ] 2+ (pn  =  1,3-diaminopropane), gives the ionic complex [Cu(pn) 2 ][Ag 3 (CN) 5 ]. Single crystal X-ray analysis shows that this complex crystallizes in the triclinic, space group , a   =  7.675(3), b   =  8.707(4), c   =  8.807(4)  Å, α   =  66.624(7), β   =  67.045(7), γ   =  79.179(7)°, Z   =  1. The whole complex has 3D architecture through metal–metal interactions and other weak interactions. The complex displays weak luminescence determined by argentophilicity at room temperature in the solid state. [ABSTRACT FROM AUTHOR]
