catena-Poly[[silver(I)-μ-4-aminopyridine] perchlorate]: a 1-D staircase coordination polymer.

Reaction of 4-amino-pyridine with silver(I) perchlorate leads to a one-dimensional coordination polymer, {[Ag(C(5)H(6)N(2))]ClO(4)}(n), in which the amino-pyridine binds through both N atoms. The perchlorate anion is hydrogen bonded to the amino H atoms and inter-acts weakly with the silver(I) atoms (Ag-O > 2.70 Å), both located on inversion centres, and some aromatic H atoms (O-H > 2.
