Synthesis and Properties of a Heteronuclear Ag(I)/Ni(II) Complex1

A complex, Ni(en)2Ag3 (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.
