catena-Poly[[[(iminodiacetato-κO)silver(I)]-μ3-2-aminopyrimidine-κ3N1:N2:N3] monohydrate]: a one-dimensional silver(I) coordination polymer with mixed ligands

The title compound, {[Ag(C4H6NO4)(C4H5N3)]center dot H2O}(n), was synthesized by the reaction of silver(I) nitrate with 2-aminopyrimidine and iminodiacetic acid. X-ray analysis reveals that the crystal structure contains a one-dimensional ladder-like Ag I coordination polymer and that N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonding results in a three-dimensional network. The Ag I centre is four-coordinated by three N atoms from three different 2-aminopyrimidine ligands and one O atom from one iminodiacetate ligand. Comparison of the structural features with previous findings suggests that the existence of a second ligand plays an important role in the construction of such polymer frameworks.
