نویسندگان
چکیده
The reaction of manganese(II) sulfate and 2-amino-pyrazine affords the title salt, [Mn(H(2)O)(6)][Mn(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 cations lie on centers of inversion in octa-hedral geometries. The cations, anions and solvent water mol-ecules are linked by O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonds into a three-dimensional network.

متن کاملtrans-Bis(acetato-κO)diaquabis(2-aminopyrazine-κN 4)manganese(II) dihydrate
The Mn(II) atom in the title compound, [Mn(CH(3)COO)(2)(C(4)H(5)N(3))(2)(H(2)O)(2)]·2H(2)O, is situated on a center of inversion and shows an octa-hedral coordination polyhedron made up by four O atoms and two N atoms. The octa-hedron is somewhat tetra-gonally distorted owing to the longer Mn-N bond [2.323 (3) Å]. The mononuclear complex mol-ecule and uncoordinated water mol-ecules are linked b...

The title compound, [Mn(C(4)H(3)N(8))(2)(H(2)O)(4)]·2H(2)O, represents the first structurally characterized transition metal complex of the 1,2-bis-(tetra-zol-5-yl)ethene ligand. The complex mol-ecule occupies a special position on an inversion centre and the Mn atom has a tetra-gonally distorted octa-hedral coordination. The bis-(tetra-zolyl)ethene ligand is planar within 0.0366 (7) Å. All 'ac...

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...
