Catena-Poly[manganese(II)-(μ(2)-3,5-di-2-pyridyl-1,2,4-triazol-ato)-μ(2)-formato].

ABSTRACT: Owing to the presence of crystallographic twofold rotation axes (site symmetry 2, Wyckoff letters e and f), the asymmetric unit of the title compound, [Mn(C(12)H(8)N(5))(CHO(2))](n), contains one-half of an Mn(II) cation, one-half of a bpt anion (Hbpt is 3,5-di-2-pyridyl-4H-1,2,4-triazole) and one-half of a formate anion. The bpt and formate ligands occupy the same C(2) symmetry, while the Mn(II) ion resides on another crystallographic twofold rotation axis. Each bpt ligand acts as a cis-bis-chelate to ligate two Mn(II) ions into a one-dimensional chain running along the crystallographic 4(1) screw axis. Adjacent Mn(II) ions are further bridged by a μ(2)-formate ligand, completing the distorted octa-hedral coordination geometry of the cation.

Project description:In the title complex, [FeMn(C(8)H(8)N(3))(2)Cl(2)(H(2)O)(2)](n), the Mn(II) atom, located on an inversion center, is octa-hedrally coordinated by two N atoms from two adjacent 1,1'-bis-(1H-1,2,4-triazol-1-ylmeth-yl)ferrocene (btmf) ligands and two Cl atoms forming the equatorial plane, with the axial positions occupied by two O atoms of coordinated water mol-ecules. The btmf ligands link adjoining Mn(II) atoms into a zigzag chain along the a axis. The crystal structure is stabilized by inter-molecular O-H⋯N hydrogen bonds, which link the chains, forming a two-dimensional layer parallel to (10); O-H⋯Cl inter-actions link the layers, forming a three-dimensional network.

4-Amino-3,5-di-2-pyridyl-4H-1,2,4-triazole.

Project description:In the crystal structure of the title compound, C(12)H(10)N(6), the mol-ecules deviate slightly from planarity. The plane of the central triazole ring makes angles of 6.13 (9) and 3.28 (10)° with the pyridyl ring planes. Intra-molecular N-H⋯N inter-actions form six-membered closed rings. The crystal packing also shows weak C-H⋯π and C-H⋯N inter-actions.

Project description:In the title compound, [Cu(C(4)HN(3)O(4))(H(2)O)(3)](2)[Cu(2)(C(4)HN(3)O(4))(2)(H(2)O)(6)], both monomeric and dimeric mol-ecules are present in the solid state. In the monomeric compound, the Cu(II) atom is five-coordinated in a square-pyramidal configuration by one O atom and one N atom from one 1H-1,2,4-triazole-3,5-dicarboxyl-ate (TZDCA(2-)) ligand and three O atoms from water mol-ecules. In the centrosymmetric binuclear complex, each Cu(II) atom is six-coordinated in an octa-hedral geometry by one O atom and one N atom from one TZDCA(2-) ligand and four O atoms from water mol-ecules, two of which bridge the Cu(II) atoms. In the structure, there are intra-molecular O-H⋯O and N-H⋯O hydrogen bonds, and in the crystal, inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds link symmetry-related mol-ecules, forming a three-dimensional supra-molecular structure.

Project description:In the polymeric title complex, {[Mn(C(8)H(4)O(4))(C(7)H(6)N(2))(H(2)O)(2)]·2H(2)O}(n), the Mn(II) cation is coordinated by two benzene-dicarboxyl-ate anions, one benzimidazole ligand and two water mol-ecules in a distorted MnNO(5) octa-hedral geometry.

One Mn-O(carboxyl-ate) bond is much longer than the others. In the crystal, π-π stacking is observed between nearly parallel [dihedral angle = 4.32 (6)°] benzimidazole aromatic ring systems of adjacent mol-ecules, the centroid-centroid distance between the imidazole and benzene rings being 3.5421 (11) Å. Extensive inter-molecular O-H⋯O and N-H⋯O hydrogen bonding is present in the crystal structure. The two lattice water mol-ecules are located on twofold rotation axes.
