Crystal structure of trans-bis-(di-ethano-lamine-?(3) O,N,O')manganese(II) bis-(3-amino-benzoate).

ABSTRACT: Reaction of m-amino-benzoic acid (MABA), di-ethano-lamine (DEA) and MnCl2·4H2O led to the formation of the title salt, [Mn(C4H11NO2)2](C7H6NO2)2. In the complex cation, the Mn(2+) ion is located on an inversion centre and is coordinated by two symmetry-related tridentate DEA mol-ecules, leading to the formation of a slightly distorted MnN2O4 octa-hedron. The MABA(-) counter-anions are connected to the complex ion by a pair of rather strong O-H?O hydrogen bonds, yielding a 1:2 supra-molecular aggregate. Much weaker N-H?O hydrogen bonds connect neighbouring aggregates into a three-dimensional network structure.

Crystal structure of bis-(tri-ethano-lamine-?(3) N,O,O')nickel(II) bis-(3-hy-droxy-benzoate) tetra-hydrate.

Project description:The reaction of 3-hy-droxy-benzoic (m-hy-droxy-benzoic) acid (MHBA), tri-ethano-lamine (TEA) and Ni(NO3)2 in aqueous solution led to formation of the hydrated title salt, [Ni(C6H15NO3)2](C7H5O3)·4H2O. In the complex cation, the Ni(2+) ion is located on an inversion centre. Two symmetry-related TEA ligands occupy all coordination sites in an N,O,O'-tridentate coordination, leading to a slightly distorted NiN2O4 octa-hedron. Two ethanol groups of each TEA ligand form two five-membered chelate rings around Ni(2+), while the third ethanol group does not coordinate to the metal atom. Two MHBA(-) anions in the benzoate form are situated in the outer coordination sphere for charge compensation. An intricate network of hydrogen bonds between the free and coordinating hy-droxy groups of the TEA ligands, the O atoms of the MHBA(-) anions and the water mol-ecules leads to the formation of a two-dimensional structure extending parallel to (010).

Crystal structure of trans-di-aqua-bis-(nicotinamide-?N (1))bis-(4-nitro-benzoato-?O)manganese(II).

Project description:The asymmetric unit of the title compound, [Mn(C7H4NO4)2(C6H6N2O)2(H2O)2], contains one Mn(II) atom, one 4-nitro-benzoate (NB) anion, one nicotinamide (NA) ligand and one water mol-ecule; NA and NB each act as a monodentate ligand. The Mn(II) atom, lying on an inversion centre, is coordinated by four O atoms and two pyridine N atoms in a distorted octa-hedral geometry. The water mol-ecules are hydrogen bonded to the carboxyl-ate O atoms. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 24.4?(3)°, while the benzene and pyridine rings are oriented at a dihedral angle of 86.63?(11)°. In the crystal, O-H?O and N-H?O hydrogen bonds link the mol-ecules, forming a layer parallel to the ab plane. The layers are further linked via weak C-H?O hydrogen bonds, a ?-? stacking inter-action [centroid-centroid distance = 3.868?(2)?Å] and a weak C-H?? inter-action, resulting in a three-dimensional network.

Crystal structure of the salt bis-(tri-ethano-lamine-κ(3) N,O,O')cobalt(II) bis-[2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetate].

Project description:The reaction of 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetic acid (NBTA) and tri-ethano-lamine (TEA) with Co(NO3)2 results in the formation of the title complex, [Co(C6H15NO3)2](C9H6NO3S)2, which is formed as a result of the association of bis-(tri-ethano-lamine)-cobalt(II) and 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetate units. It crystallizes in the monoclinic centrosymmetric space group P21/c, with the Co(II) ion situated on an inversion centre. In the complex cation, the Co(II) ion is octa-hedrally coordinated by two N,O,O'-tridentate TEA mol-ecules with a facial distribution and the N atoms in a trans arrangement. Two ethanol groups of each TEA mol-ecule form two five-membered chelate rings around the Co(II) ion, while the third ethanol group does not coordinate to the metal. The free and coordinating hy-droxy groups of the TEA mol-ecules are involved in hydrogen bonding with the O atoms of NBTA anions, forming an infinite two-dimensional network extending parallel to the bc plane.

It has a coordination number of 4, is in a distorted tetra-hedral environment and is connected by the bridging oxygen atoms of the deprotonated OH groups of different amino-alcohol groups, and by the N atoms of deprotonated di-methyl-pyrazole ligands. The peripheral Cu atom is in a trigonal-bipyramidal coordination environment formed by the nitro-gen atom of the deprotonated bridging di-methyl-pyrazole unit, the bridging oxygen atom of the deprotonated OH group, two oxygen atoms of the protonated hy-droxy groups and the nitro-gen atom of tri-ethano-lamine. One of the C atoms and the Br- anion were found to be disordered over two positions with occupancy factors of 0.808 (9):0.192 (9) and 0.922 (3):0.078 (3), respectively.

Crystal structure of di-ethano-lbis(thio-cyanato)-bis(urotropine)cobalt(II) and tetra-ethano-lbis(thio-cyanato)-cobalt(II)-urotropine (1/2).

Project description:The reaction of one equivalent Co(NCS)2 with four equivalents of urotropine (hexa-methyl-ene-tetra-mine) in ethanol leads to the formation of two compounds, namely, bis-(ethanol-κO)bis-(thio-cyanato-κN)bis-(urotropine-κN)cobalt(II), [Co(NCS)2(C6H12N4)2(C2H6O)2] (1), and tetra-kis-(ethanol-κO)bis-(thio-cyanato-κN)cobalt(II)-urotropine (1/2), [Co(NCS)2(C2H6O)4]·2C6H12N4 (2). In 1, the Co cations are located on centers of inversion and are sixfold coordinated by two terminal N-bonded thio-cyanate anions, two ethanol and two urotropine ligands whereas in 2 the cobalt cations occupy position Wyckoff position c and are sixfold coordinated by two anionic ligands and four ethanol ligands. Compound 2 contains two additional urotropine solvate mol-ecules per formula unit, which are hydrogen bonded to the complexes. In both compounds, the building blocks are connected via inter-molecular O-H⋯N (1 and 2) and C-H⋯S (1) hydrogen bonding to form three-dimensional networks.

Crystal structure of trans-bis-[2-(1H-benzotriazol-1-yl)acetato-?O]bis-(ethano-lamine-?2 N,O)copper(II).

Project description:The reaction of 2-(1H-benzotriazol-1-yl)acetic acid (HBTA; C8H7N3O2) and mono-ethano-lamine (MEA; C2H7NO) with CuCl2·2H2O resulted in the formation of the title complex, [Cu(C8H6N3O2)2(C2H7NO)2] or [Cu(BTA)2(MEA)2]. Its asymmetric unit comprises one BTA anion coordin-ating to the Cu2+ cation (site symmetry ) through the carboxyl O atom, and one MEA ligand chelating the metal cation by two heteroatoms (O and N). The equatorial Cu-O and Cu-N bond lengths are similar at 2.029?(1) and 1.980?(2)?Å, respectively, while the length of the axial Cu-O bond is considerably greater [2.492?(2)?Å], as is typical for Jahn-Teller-distorted systems. An intra-molecular hydrogen bond is present between the hy-droxy group of the MEA ligand and the non-coordinating O atom of the carboxyl-ate group. Inter-molecular hydrogen bonding involving the amino function of the MEA ligand and the carboxyl-ate group results in eight-membered rings with an R 2 2(8) graph-set motif. The mol-ecules are further linked by C-H?? inter-actions involving the triazole rings and methyl-ene groups of MEA, thus generating an overall three-dimensional supra-molecular framework.

catena-Poly[[trans-bis-(1,3-benzo-thia-zole-?N)manganese(II)]-di-?-chlorido].

Project description:In the title coordination polymer, [MnCl2(C7H5NS)2] n , the Mn(II) ion is located on the inter-section of a twofold rotation axis and a mirror plane and adopts an octa-hedral coordination geometry defined by two mutually trans N atoms from benzo-thia-zole ligands which occupy the axial positions, and four Cl atoms which form the equatorial sites. The Mn(II) ions are connected by two bridging Cl atoms, forming chains parallel to the c axis. The crystal packing can be descibed as alternating layers parallel to (001) featuring ?-? stacking inter-actions with a centroid-centroid distance of 3.6029?(15)?Å.
