catena-Poly[[bis-(nitrato-κO,O')zinc(II)]-μ-4,4'-bis-(pyrazol-1-ylmeth-yl)biphenyl-κN:N]
Abstract:
In the title compound, [Zn(NO(3))(2)(C(20)H(18)N(4))](n), the Zn(II) atom lies on a crystallographic twofold axis and the coordination geometry can be considered as a slightly distorted tetra-hedron defined by two O atoms from two nitrate groups and two N atoms from two ligand mol-ecules. A distorted octa-hedron may be assumed when two of the symmetry-related nitrate O atoms, with Zn-O distances of 2.528 (2) Å, are added to the coordination environment. Another twofold axis, passing through the middle of the biphenyl bonds, is observed in the crystal structure. A chain along [101] is built up by the ligands linking the Zn(II) ions.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
