Bis[5-(pyridin-2-yl)pyrazine-2-carbo-nitrile-?N,N]silver(I) perchlorate.


ABSTRACT: In the mononuclear title complex, [Ag(C(10)H(6)N(4))(2)]ClO(4), the Ag(I) ion is surrounded by two 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands, forming a considerably distorted square-planar N(4)-coordination geometry, with two short and two long Ag-N distances. Each perchlorate anion links two mononuclear coordination units through C-H?O(perchlorate) hydrogen bonding, forming an infinite tape structure along [110]. Inter-molecular ?-? stacking inter-actions between adjacent pyridine and pyrazine rings [centroid-centroid distances of 3.777?(3) and 3.879?(2)?Å] further assemble the tape motifs into a three-dimensional supra-molecular structure.
