STRUCTURE OF [2-(AMINOMETHYL)PYRIDINE] SILVER(I) NITRATE AND EPR STUDIES OF ITS OXIDATION-PRODUCT

Reaction of AgNO3 with excess 2-(aminomethyl)pyridine (amp) in water l ed to the crystallization of Ag(amp)NO3 (1). Nearly linear coordinatio n of silver(I) by pyridine-N and amino-N from two different amp molecu les results in a polymeric chain structure of 1. The packing is stabil ized by ring-ring stacking interactions between two inversion-related polymer chains. Oxidation of 1 with (NH4)(2)S2O8 resulted in an orange solution from which a magnetically dilute Ag-II complex was crystalli zed by the addition of NH4PF6. It gave a well-resolved EPR spectrum la nd is formulated as silver(II) picolinate co-crystallized with NH4PF6. Copyright (C) 1996 Elsevier Science Ltd
