Bis[5-(pyridin-2-yl)pyrazine-2-carbonitrile-κ2 N 4,N 5]silver(I) perchlorate

چکیده
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 π-π 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.

In the asymmetric unit of the title compound, [Ag(C(10)H(6)N(4))(2)(CF(3)CO(2))], there two mononuclear but slightly different complex units. In each, two κ(2)N:N-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, giving an N(4)O square-pyramidal coordination geometry with one trifluoro-acetate O atom at the apex. The difference between the two lies in the Ag-N b...
