trans-Diaqua(pyridazine-3-carboxylato-κ²N²,O)lithium

Abstract

The structure of the title complex, [Li(C5H3N2O2)(H2O)2], is built of monomeric mol­ecules. In each, an Li+ ion is N,O-chelated by the pyridazine-3-carboxyl­ate ligand and two water O atoms. The coordination geometry of the metal ion is distorted tetra­hedral. The monomers are linked by a system of hydrogen bonds in which water mol­ecules act as donors and carboxyl­ate O atoms act as acceptors. O—H⋯N hydrogen bonding is also present.
