Poly[[(μ(3)-2,4,6-tri-4-pyridyl-1,3,5-triazine)copper(I)] nitrate monohydrate].

In the title compound, {[Cu(C(18)H(12)N(6))]NO(3)·H(2)O}(n), the Cu(I) ion is coordinated by three N atoms [Cu-N 1.962 (3)-2.019 (3) Å] from three 2,4,6-tri-4-pyridyl-1,3,5-triazine (L) ligands. Each L ligand bridges three Cu(I) atoms, generating a positively charged three-dimensional polymeric network with voids propagated along the b axis. These voids are filled with NO(3) (-) anions with a shortest Cu⋯O distance of 2.645 (3) Å and water mol-ecules, which are linked into negatively charged helical chains via inter-molecular O-H⋯O hydrogen bonds.
