Tetra-aqua-bis-(2-methyl-1H-benzimidazolium-1,3-diacetato-κO)cobalt(II) tetra-hydrate.

ABSTRACT: In the title compound, [Co(C(12)H(11)N(2)O(4))(2)(H(2)O)(4)]·4H(2)O, the Co(II) atom lies on an inversion center and is octa-hedrally coordinated by six O atoms from four water mol-ecules and two monodentate zwitterionic 2-methyl-benzimidazolium-1,3-diacetate ligands. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π inter-actions between the imidazole and benzene rings [centroid-centroid distance = 3.9031 (17) Å] consolidate the crystal packing.

Tetra-aqua-bis(2-methyl-benzimidazolium-1,3-diacetato-κO)zinc(II) tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Zn(C(12)H(11)N(2)O(4))(2)(H(2)O)(4)]·4H(2)O, contains one-half of the complex mol-ecule and two uncoordin-ated water mol-ecules. The four water O atoms in the equatorial plane around the Zn(II) centre ( symmetry) form a distorted square-planar arrangement, while the distorted octa-hedral coordination geometry is completed by the O atoms of the zwitterionic 2-methyl-benzimidazolium-1,3-diacetate ligands in the axial positions. The benzimidazole ring system is planar, with a maximum deviation of 0.041 (3) Å. Intra-molecular O-H⋯O hydrogen bonding results in the formation of a non-planar six-membered ring. In the crystal structure, strong intra- and inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π contacts between benzimidazole rings [centroid-centroid distance = 3.899 (1) Å] may further stabilize the structure.

Tetra-aqua-bis-(3,5-dinitro-benzoato-κO (1))magnesium tetra-hydrate.

Project description:In the structure of the title compound, [Mg(C7H3N2O6)2(H2O)4]·4H2O, the slightly distorted octa-hedral MgO6 coord-in-ation polyhedron comprises two trans-related carboxyl-ate O-atom donors from mononodentate 3,5-dinitro-benzoate ligands, and four water mol-ecules. The coordinating water mol-ecules and the four water mol-ecules of solvation give both intra- and inter-unit O-H⋯O hydrogen-bonding inter-actions with carboxyl-ate, water and nitro O-atom acceptors, forming a three-dimensional structure.

cyclo-Tetra-μ-malato-κO,O',O'':O'''-tetra-kis[bis-(1H-benzimidazole-κN)cobalt(II)] eicosa-hydrate.

Project description:The title compound, [Co(4)(C(4)H(4)O(5))(4)(C(7)H(6)N(2))(8)]·20H(2)O, consists of tetra-nuclear Co(II) complexes and disordered uncoordinated water mol-ecules. The tetra-meric complex mol-ecule has symmetry. While two benzimidazole mol-ecules and a tridentate malate dianion coordinate a Co(II) ion, the carboxylate O atom from an adjacent malate dianion bridges the Co(II) ions to complete a distorted octa-hedral coordination geometry. The tridentate malate dianion chelates the Co(II) ion, and the chelate six- and five-membered rings show half-chair and envelope configurations, respectively. A face-to-face separation of 3.494 (9) Å between parallel benzimidazole ligands indicates the existence of π-π stacking between adjacent complexes. The crystal structure also involves N-H⋯O and O-H⋯O hydrogen bonds.

Bis[tetra-aqua-(1,10-phenanthroline-?N,N')cobalt(II)] hexa-aqua-cobalt(II) bis-[3,5-bis-(carboxyl-atometh-oxy)benzoate] tetra-hydrate.

Project description:The title compound, [Co(C(12)H(8)N(2))(H(2)O)(4)](2)[Co(H(2)O)(6)](C(11)H(7)O(8))(2)·4H(2)O, was obtanied by the reaction of cobalt acetate with 3,5-bis-(carb-oxy-meth-oxy)benzoic acid and 1,10-phenanthroline. The asymmetric unit contains one tetra-aqua-(1,10-phenanthroline)cobalt(II) cation, one half of a hexa-aqua-cobalt(II) cation that is completed by inversion symmetry, one 3,5-bis-(carboxyl-atometh-oxy)benzoate trianion and two lattice water mol-ecules. The two Co(II) atoms each show a slightly distorted octa-hedral coordination (CoO(6) and CoO(4)N(2)). The cations, anions and lattice water mol-ecules are linked by an intricate network of O-H?O hydrogen bonds into a three-dimensional structure.

Bis(?-imino-diacetato)bis-[(2,2'-diamino-4,4'-bi-1,3-thia-zole)lead(II)] tetra-hydrate.

Project description:In the crystal structure of the title compound, [Pb(2)(C(4)H(5)NO(4))(2)(C(6)H(6)N(4)S(2))(2)]·4H(2)O, the dinuclear Pb(II) complex mol-ecule is centrosymmetric. The Pb atom is chelated by a tridentate imino-diacetate anion (IDA) and a diamino-bithia-zole (DABT) ligand, while a carboxyl-ate O atom from an adjacent IDA anion further bridges the Pb atom with a longer Pb-O bond [2.892?(3)?Å]. The lone-pair electrons of the Pb atom occupy an axial site in the ?-penta-gonal-bipyramidal coordination polyhedron. The IDA anion displays a facial configuration: its chelating five-membered rings assume an envelope configuration. Within the DABT ligand, the two thia-zole rings are twisted relative to each other, making a dihedral angle of 9.51?(17)°. Extensive N-H?O, O-H?O and weak C-H?O hydrogen bonding helps to stabilize the crystal structure.

trans-Tetra-aqua-bis-(isonicotinamide-?N)cobalt(II) bis-(3-hy-droxy-benzoate) tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(7)H(5)O(3))(2)·4H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 3-hy-droxy-benzoate counter-anion and two uncoordinated water mol-ecules. Four water O atoms in the equatorial plane around the Co(II) ion [Co-O = 2.0593?(16) and 2.1118?(16)?Å] form a slightly distorted square-planar arrangement, and the distorted octahedral geometry is completed by the two N atoms [Co-N = 2.1306?(18)?Å] from two isonicotinamide ligands. In the anion, the carboxyl-ate group is twisted from the attached benzene ring at 8.84?(17)°. In the crystal, a three-dimensional hydrogen-bonding network, formed by classical O-H?O and N-H?O hydrogen bonds, consolidates the crystal packing, which exhibits ?-? inter-actions between the benzene and pyridine rings, with centroid-centroid distances of 3.458?(1) and 3.606?(1)?Å, respectively.

Tetra-aqua-bis-(6-chloro-pyridine-3-carboxyl-ato-κO)nickel(II) tetra-hydrate.

Project description:In the title compound, [Ni(C(6)H(3)ClNO(2))(2)(H(2)O)(4)]·4H(2)O, the Ni(II) ion is located on an inversion centre and is octa-hedrally coordinated by four O atoms from four water mol-ecules in the equatorial plane and two O atoms of two 6-chloro-3-carboxyl-ate ligands in axial positions. There are also four lattice water molecules present. The organic ligands are bound to the Ni(II) ion in a monodentate manner through a carboxyl-ate O atom. There is one strong intra-molecular O-H⋯O hydrogen bond and six inter-molecular O-H⋯O and O-H⋯N hydrogen-bonding inter-actions in the packing, resulting in a complex three-dimensional network structure.
