Anion dependent silver(i) complexes of pyrazine mono-N-oxide

Abstract

Pyrazine mono-N-oxide shows a clear preference for coordination to silver(I) through the nitrogen atom. However, in some cases it acts as an N,O-bridging ligand to form 1D coordination polymers. The specific species formed is dependent on the nature of the counteranion. In general, the complexes formed have additional weak interactions that appear to control the crystal packing.
