ABSTRACT: In the title compound, [Zn(C(7)H(6)NO(2))(2)(H(2)O)(2)], the Zn atom (site symmetry ) adopts a distorted trans-ZnN(2)O(4) octa-hedral coordination arising from two N,O-bidentate 5-methyl-pyridine-2-carboxyl-ate ligands and two water mol-ecules. In the crystal structure, mol-ecules form a layered network linked by O-H?O hydrogen bonds.

Project description:In the title compound, [Zn(C(10)H(4)Cl(2)NO(2))(2)(H(2)O)(2)]·H(2)O, the Zn atom has a distorted square-pyramidal geometry comprising two O atoms and one N atom from two distinct 3,7-dichloro-quinoline-8-carboxyl-ate ligands, and two water mol-ecules. The free water mol-ecules are involved in inter-molecular O-H?O hydrogen bonding with the coordinated water mol-ecules and carboxyl-ate O atoms, to give a one-dimensional helical chain along the [100] direction.

Diaqua-bis-(pyridine-2-carboxyl-ato-κN,O)manganese(II) dimethyl-formamide hemisolvate.

Project description:There are two crystallographically independent complex mol-ecules with very similar geometries in the unit cell of the title compound, [Mn(C(6)H(4)NO(2))(2)(H(2)O)(2)]·0.5C(3)H(7)NO. The central ion is situated in a distorted octa-hedral environment of two N- and four O-donor atoms from two pyridine-2-carboxyl-ate ligands and two cis-disposed water mol-ecules. The carboxyl-ate ligands are coordinated in a chelate fashion with the formation of two five-membered rings. In the crystal, the complex mol-ecules are connected by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate O atoms, thus forming hydrogen-bonded walls disposed perpendicularly to the bc plane.

Project description:In the title complex, [Co(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O, the coordination geometry of the Co(2+) cation is distorted octa-hedral, with two N atoms and two O atoms from two 5-methyl-pyrazine-2-carboxyl-ate ligands in the equatorial plane. The two remaining coordination sites are occupied by two water mol-ecules. In addition, there are two uncoordinated water mol-ecules in the asymmetric unit. The crystal structure is stabilized by a network of O-H?O and O-H?N hydrogen-bonding inter-actions, forming a three-dimensional structure.

Hexaaqua-zinc(II) bis-[tris-(3-carb-oxy-pyridine-2-carboxyl-ato)zincate(II)].

Project description:The title compound, [Zn(H(2)O)(6)][Zn(C(7)H(4)NO(4))(3)](2), consists of two [Zn(py-2,3-dcH)(3)](-) anions (py-2,3-dcH is 3-carboxy-pyridine-2-carboxylate) and one [Zn(H(2)O)(6)](2+) cation. The anion is a six-coordinate complex located on a threefold rotation axis with a slightly distorted octa-hedral geometry around Zn(2+) ion. The cation is also six-coordinate with an octa-hedral geometry around the Zn atom, located at a axis. Non-covalent inter-actions such as ?-? stacking [centroid-centroid distance = 3.828?(4)Å] and O-H?O hydrogen bonds play important roles in stabilizing the supra-molecular structure.
