Synthesis and Properties of a Heteronuclear Ag(I)/Ni(II) Complex

A complex, Ni(en) 2 Ag 3 (CN) 5 (en = ethylenediamine), was obtained through the reaction of [Ag (CN) 2 ] − units with Ni II-diamine cation [Ni(en) 2 ] 2+ , and the structure was determined by single crystal X-ray diffraction. It is indicated that the complex has a 3D architecture through the silver-silver interactions and the bridging cyano groups. This complex displays interesting luminescent properties caused by argentophilicity at room temperature in solid state.
