Hexaaquacobalt(II) tetraaquabis(2-aminopyrazine-κN 4)cobalt(II) disulfate dihydrate
نویسندگان
چکیده
The reaction of cobalt(II) sulfate and 2-amino-pyrazine affords the title salt, [Co(H(2)O)(6)][Co(C(4)H(5)N(3))(2)(H(2)O)(4)](SO(4))(2)·2H(2)O. The metal atoms in the tetra-aqua-coordinated and hexa-aqua-coordinated complex cations lie on centers of inversion in slightly distorted octa-hedral geometries. The cations, anions and solvent water mol-ecules are linked by O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.

The Co(II) atom in the title compound, [Co(C(12)H(8)N(5))(2)(H(2)O)(4)]·2H(2)O, lies on a center of inversion and is bonded to two N-heterocycles and to four water mol-ecules in a slightly distorted octahedral coordination. The coordinated and lattice water mol-ecules inter-act with the N-heterocycles through O-H⋯N hydrogen bonds, generating a three-dimensional supra-molecular architecture.

In the title coordination polymer, {[BaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(4)]·2H(2)O}(n), the Ba(2+) cation is deca-coordinate, ligated by four aqua ligands and four [Cu(C(9)H(4)O(5)N)(C(3)H(4)N(2))] 'complex ligands'. The Cu(II)-containing complex-ligands are bridged by the Ba(2+) cations, resulting in a one-dimensional polymeric chain structure. The crystal structure is maintaine...

The asymmetric unit of the crystal structure of the title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(8)H(5)O(3))(2)·2H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 4-formyl-benzoate (FB) counter-anion and an uncoordinated water mol-ecule. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar ...
