“…The coordination of the Zn(II) ion by a N,O bonding moiety is also observed in the structures of its complexes with azine carboxylate ligands such as cis-bisaquadi(pyridine-3-carboxylato-N,O)-zinc(II) tetrahydrate [12], trans-bisaquadi [4]. In all of them the zinc ion is coordinated octahedrally.…”

“…Our previous crystal structure studies of Mg(II) and Zn(II) complexes with diazine monocarboxylate ligands [1][2][3][4][5] will be composed of monomeric molecules, the metal ions will be chelated by the N,O bonding moieties donated by the ligand molecules and the coordination will be octahedral. Therefore, continuing our crystal-chemical studies on divalent metal complexes with heterocycle carboxylate ligands, the crystal structures of Mg(II) and Zn(II) imidazolates have been determined.…”

Magnesiumimidazolate: trans-diaquabis(imidazole-4-carboxylato-2 N,O)-magnesium(II) Mg(C 4 H 3 N 2 O 2 ) 2 (H 2 O) 2 crystallizes in the monoclinic system (space group P2 1 /c). The structure is composed of monomeric molecules, each containing a Mg(II) ion located at the inversion centre and chelated by two imidazole-4-carboxylate ligand molecules via their N,O bonding moieties (Mg-N 2.193(2)Å 0 , Mg-O 2.070(2)Å 0 ) and two water oxygen atoms (Mg-O 2.063(2)Å 0 . A fairly regular octahedron with water oxygen atoms at the apical positions is formed. The monomers are kept together by hydrogen bonds. Triclinic unit cell (space group P 1) of zinc imidazolate: [trans-diaquabis(imidazole-4-carboxylato-2 N,O)-zinc(II)] [monoaquabis(imidazole-4-carboxylato-N,O)-zinc(II)] trihydrate [Zn(C 4 H 3 N 2 O 2 ) 2 (H 2 O) 2 ][Zn(C 4 H 3 N 2 O 2 ) 2 (H 2 O)] Á 3H 2 O contains two monomeric complex molecules in which the Zn(II) ion is octahedrally coordinated by two trans ligand molecules and two water oxygen atoms. The unit cell also contains two monomeric complex molecules in which the Zn(II) ion is pentacoordinate with two ligand molecules and one water oxygen atom. Six solvation water molecules complete the content of the unit cell. Mean bond distances in the pentacoordinated Zn(II) polyhedron are: 2.101(2)Å 0 (Zn-O), 2.040(2)Å 0 (Zn-N) and 2.002(3)Å 0 (Zn-O water ). An extended network of hydrogen bonds is responsible for the stability of the structure.

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

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.
