Dimethyl-ammonium diaqua-(pyridine-2,4-dicarboxyl-ato-κN,O)cuprate(II)
Abstract:
The asymmetric unit of the title compound, (C(2)H(8)N)(2)[Cu(C(7)H(3)NO(4))(2)(H(2)O)(2)], contains one-half of a mononuclear [Cu(C(7)H(3)NO(4))(2)(H(2)O)(2)](2-) anion, one dimethyl-ammonium cation and one aqua ligand. The Cu(II) atom, lying on an inversion center, is coordinated by two symmetry-related N atoms and two O atoms from one pyridine-2,4-dicarboxyl-ate ligand and two symmetry-related aqua ligands and exhibits a distorted octa-hedral trans-[CuN(2)O(4)] coordination geometry. Multiple crystallographically independent O-H⋯O and N-H⋯O hydrogen bonds form a three-dimensional network in the crystal structure.

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...
