The silver (I) complex of pyrazine-2,3-dicarbonitrile (dcpz), [Ag (dcpz)] (ClO 4 ) has been prepared and the molecular structure determined by X-ray crystallography. The silver ion prefers an octahedral coordination geometry comprising four nitrogen atoms from four different dcpz molecules and two oxygen atoms from ClO 4- anion. Each dcpz in turn bridges four Ag (I) centres leading...
