Diaqua-bis-(4-hy-droxy-5-nitro-pyridine-2-carboxyl-ato-?N,O)copper(II).

ABSTRACT: In the title compound, [Cu(C(6)H(3)N(2)O(5))(2)(H(2)O)(2)], the Cu(II) ion, lying on an inversion center, is coordinated by two pyridine N atoms and two carboxyl-ate O atoms from symmetry-related two 4-hy-droxy-5-nitro-pyridine-2-carboxyl-ate ligands, and two water mol-ecules, forming a distorted octa-hedral geometry. In the crystal, O-H?O hydrogen bonds link the complex mol-ecules. One of the H atoms of the water mol-ecule is disordered over two sites of equal occupancy.

Project description:The title compound, [Cu(2)(C(7)H(3)NO(5))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a centrosymmetric binuclear molecule. Each completely deprotonated 4-hy-droxy-pyridine-2,6-dicarb-oxy-lic acid mol-ecule assumes a tridentate chelating coordination mode. The square-pyramidal coordination geometry around the Cu(II) ion is completed by the bridging bipyridine ligand and an apical water molecule. Adjacent complexes are connected via O-H?O and C-H?O hydrogen bonds to generate a three-dimensional supra-molecular structure.

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.

Two half-mol-ecules of 4,4'-bipyridine coordinate the Co(II) atoms from the upside and underside. The packing features extensice O-H?O hydrogen bonding.
