catena-Poly

In the title complex, [Ag(C(12)H(10)N(2))]NO(3)(n), the Ag atom, which is in a linear AgN(2) geometry, is surrounded by two trans-related N atoms of two bpe ligands [Ag-N = 2.173 (3) and 2.176 (3) A; bpe is trans-1,2-bis(2-pyridyl)ethylene]. The bpe ligands bridge neighbouring Ag atoms to form zigzag polymeric chains in the lattice. These adjacent one-dimensional zigzag chains are extended into a three-dimensional supramolecular array by strong interchain pi.pi interactions between the pyridyl rings of adjacent chains.
