“….2H 2 O, crystallizes in the triclinic crystal system, space group P-1, and it is isostructural with the zinc and manganese complexes previously reported by Gryz et al (2003) and Ardiwlnata et al (1989). As expected, the Co-O and Co-N distances (Table 1) are similar to those of the Zn(II) and Mn(II) analogues.…”

Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.003 Å; R factor = 0.026; wR factor = 0.058; data-to-parameter ratio = 11.2.The title compound, [Co(C 5 II ion on an inversion center, exhibiting an octahedral coordination geometry. The equatorial plane is formed by two trans-related N,O-bidentate pyridazine-3-carboxylate ligands and the axial positions are occupied by two water molecules. The Co II complex molecules are stacked in a column along the a-axis direction by an O-HÁ Á ÁN hydrogen bond between the non-coordinating pyridazine N atom and the coordinating water molecule. These columns are further connected into a layer parallel to the ac plane by additional hydrogen bonds involving the coordinating and non-coordinating water molecules, and the non-coordinating carboxylate O atom. The crystal packing is completed by interlayer weak C-HÁ Á ÁO interactions. Related literature ExperimentalCrystal data [Co(C 5

“…Monomeric molecules with octahedral coordination geometry have been reported in the structures of a Mn complex (Ardiwinata et al 1989), two Zn complexes (Gryz et al, 2003(Gryz et al, , 2004) and a Mg complex (Gryz et al, 2006). On the other hand, the structure of a Ca complex is built of binuclear molecules (Starosta & Leciejewicz, 2007).…”

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.
