Crystal structure of bis-(?-N-hy-droxy-picolin-amid-ato)bis-[bis-(N-hy-droxy-picolinamide)-sodium].

ABSTRACT: The title compound, [Na₂(C₆H₅N₂O₂)₂(C₆H₆N₂O₂)₄], is a centrosymmetric coordination dimer based on the sodium(I) salt of N-hy-droxy-picolinamide. The mol-ecule has an {Na₂O₆(?-O)₂} core with two bridging carbonyl O atoms and two hydroxamate O atoms of two mono-deprotonated residues of N-hy-droxy-picolinamide, while two neutral N-hy-droxy-picolinamide mol-ecules are coordinated in a monodentate manner to each sodium ion via the carbonyl O atoms [the Na-O distances range from 2.3044?(2) to 2.3716?(2)?Å]. The penta-coordinated sodium ion exhibits a distorted trigonal-pyramidal coordination polyhedron. In the crystal, the coordination dimers are linked into chains along the c axis via N-H?O and N-H?N hydrogen bonds; the chains are linked into a two-dimensional framework parallel to (100) via weak C-H?O and ?-? stacking inter-actions.

Crystal structure of N-hy-droxy-picolinamide monohydrate.

Project description:The crystal structure of the title compound, C6H6N2O2·H2O, consists of N-hy-droxy-picolinamide and water mol-ecules connected through O-H⋯O and N-H⋯N hydrogen bonds. The O-H⋯O inter-actions and π-π stacking inter-actions between the pyridine rings [centroid-centroid distance = 3.427 (1) Å] organize the components into columns extending along the b axis and the N-H⋯N hydrogen bonds link these columns into a two-dimensional framework parallel to (100). The N-hy-droxy-picolinamide mol-ecule adopts a strongly flattened conformation and only the O-H group H atom deviates significantly from the mol-ecule best plane. The dihedral angle between the hydroxamic group and the pyridine ring is 5.6 (2)°. The conformation about the hydroxamic group C-N bond is Z and that about the C-C bond between the pyridine and hydroxamic groups is E.

Project description:The title coordination compound, {[Co(C(11)H(15)O(3))(4)(C(10)H(8)N(2))(2)(H(2)O)]·7H(2)O}(n), consists of a pair of Co(II) atoms, four 3-hy-droxy-adamantane-1-carboxyl-ate anions (L), one water mol-ecule, two bridging 4,4'-bipyridine (4,4'-bpy) ligands and seven uncoordinated water mol-ecules. Both of the Co(II) ions are coordinated in a distorted octa-hedral geometry. Four L ligands bind to each pair of Co(II) atoms in a plane, two of which bridge the two Co(II) atoms as bidentate groups while the other two coordinate to a single Co(II) atom in a monodentate mode. Two half-mol-ecules of 4,4'-bipyridine coordinate the Co(II) atoms from the upside and underside. The packing features extensice O-H?O hydrogen bonding.

Poly[[nona-aqua-bis-(?-5-hy-droxy-benzene-1,3-di-carboxyl-ato)(5-hy-droxy-benzene-1,3-di-carboxyl-ato)dicerium(III)] hexa-hydrate].

Project description:In the title coordination polymer, {[Ce2(C8H4O5)3(H2O)9]·6H2O} n , the asymmetric unit is formed by two Ce(III) atoms, three 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands, nine coordinating water mol-ecules and six water mol-ecules of crystallization. The two Ce(III) atoms are bridged by 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands acting in a bis-bidentate coordination mode, generating infinite chains along [101]. Both independent metal atoms are nine-coordinated, one by four O atoms from the carboxyl-ate groups of two bridging 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands and five O atoms from water mol-ecules, generating a tricapped trigonal-prismatic geometry. The coordination around the second Ce(III) atom is similar, except that one of the water mol-ecules is replaced by an O atom from an additional 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligand acting in a monodentate coordination mode and forming a capped square-anti-prismatic geometry.

?-4,4'-Bipyridine-bis-[aqua-(4-hy-droxy-pyridine-2,6-dicarboxyl-ato)copper(II)].

Project description:The title compound, [Cu(2)(C(7)H(3)NO(5))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a centrosymmetric binuclear molecule. Each completely deprotonated 4-hy-droxy-pyridine-2,6-dicarb-oxy-lic acid mol-ecule assumes a tridentate chelating coordination mode. The square-pyramidal coordination geometry around the Cu(II) ion is completed by the bridging bipyridine ligand and an apical water molecule. Adjacent complexes are connected via O-H?O and C-H?O hydrogen bonds to generate a three-dimensional supra-molecular structure.

Project description:Each Sc3+ ion in the title salt, di-?-hydroxido-bis-[tri-aqua-(nitrato-?2 O,O')scandium(III)] dichloride, [Sc2(NO3)2(OH)2(H2O)6]Cl2, is coordinated by a nitrate anion, two hydroxide ions and three water mol-ecules to generate a distorted penta-gonal-bipyramidal ScO7 coordination polyhedron. The complete {[(NO3)(?-OH)Sc(H2O)3]2}2+ ion is generated by crystallographic inversion symmetry. The nitrate anion binds in a bidentate fashion whereas the hydroxide ions are bridged between two Sc centers. Two charge-balancing Cl- ions are located in the outer sphere. In the extended structure, O-H?O and O-H?Cl hydrogen bonds connect the components into a three-dimensional network.

The hexa-aqua-nickel(II) cation inter-acts through hydrogen bonding with eight QOH mol-ecules and two water mol-ecules. The six-membered rings of quinoline show π-π stacking [centroid-to-centroid distances of 3.679 (2) Å and 3.714 (2) Å].

Project description:In the title compound, (C(10)H(10)NO)(2)[Ni(C(7)H(3)NO(4))(2)]·CH(3)OH·H(2)O, the coordination geometry of the Ni(II) atom can be described as distorted octa-hedral. In the crystal, noncovalent inter-actions play an important role in the stabilization of the structure, involving O-H?O, N-H?O and weak C-H?O hydrogen bonds and ?-? stacking inter-actions between the pyridine rings of the pyridine-2,6-dicarboxyl-ate ligands [centroid-centroid distance = 3.7138?(15)?Å] and between the 8-hy-droxy-2-methyl-quinolinium cations [centroid-centroid distances = 3.6737?(15), 3.4434?(14), 3.6743?(15), 3.7541?(16), 3.5020?(15) and 3.7947?(15)?Å].

Bis(8-hy-droxy-2-methyl-quinolinium) bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II) methanol monosolvate monohydrate.

Project description:The title compound, (C(10)H(10)NO)(2)[Cu(C(7)H(3)NO(4))(2)]·CH(3)OH·H(2)O was prepared by the reaction of copper(II) nitrate hexa-hydrate, 8-hy-droxy-2-methyl-quinoline, and pyridine-2,6-dicarb-oxy-lic acid in a 1:2:2 molar ratio in an aqueous solution. The geometry of the resulting CuN(2)O(4) coordination can be described as distorted octa-hedral. In the crystal, there are several inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds. An intra-molecular N-H?O hydrogen bond occurs in one of the cations. Considerable ?-? stacking inter-actions are also observed between the aromatic rings of the cations, with centroid-centroid distances of 3.4567?(13), 3.5342?(14), 3.6941?(14) and 3.4568?(13)?Å. These non-covalent inter-actions connect the components, forming a three-dimensional supra-molecular structure.
