Nitrate and nitrite silver complexes with weakly coordinating nitriles

Abstract

The structures and luminescent properties of silver(I) complexes with weakly coordinating nitrile ligands: 1,4-dicyanobenzene (1,4-dcb) and 3-cyanopyridine (3-cpy) and nitrite or nitrate coordination are investigated. One molecular complex [Ag(3-cpy)2(NO2)], one 1-D coordination polymer [Ag(3-cpy)2NO3]∞ and two rare 2-D [Ag3(3-cpy)2(NO2)3]∞ and 3-D [Ag2(1,4-dcb)(NO3)2]∞ coordination polymers are described. Coordination of the luminescent ligands does not enhance their emission properties, however extension of coordination network may lead to new emission bands in the visible region.
