Crystal structure of catena-poly[[[tri-aqua-(4-cyano-benzoato-?O)nickel(II)]-?-4,4'-bi-pyridine-?(2) N:N'] 4-cyano-benzoate].

ABSTRACT: In the title polymeric complex salt, {[Ni(C8H4NO2)(C10H8N2)(H2O)3](C8H4NO2)} n , the Ni(II) cation is coordinated by a 4-cyano-benzoate anion, two 4,4'-bi-pyridine ligands and three water mol-ecules in a distorted N2O4 octa-hedral geometry. The 4,4'-bi-pyridine ligands bridge the Ni(II) cations to form polymeric chains of the title complex cations, propagating along the c-axis direction. The dihedral angle between the pyridine rings of the 4,4'-bi-pyridine ligand is 24.9?(6)°. In the crystal, the uncoordinating 4-cyano-benzoate anions link with the complex cations via O-H?O hydrogen bonds into a three-dimensional supra-molecular architecture. Weak C-H?O, C-H?N inter-actions and ?-? stacking [centroid-to-centroid distances = 3.566?(4) and 3.885?(4)?Å] are also observed in the crystal.

Crystal structure of tri-aqua-(4-cyano-benzoato-κ(2) O,O')(nicotinamide-κN (1))zinc 4-cyano-benzoate.

Project description:The asymmetric unit of the title salt, [Zn(C8H4NO2)(C6H6N2O)(H2O)3](C8H4NO2), contains one complex cation and one 4-cyano-benzoate (CNB) counter-anion. The Zn(II) atom in the cation is coordinated by one 4-cyano-benzoate ligand, one nicotinamide (NA) ligand and three water mol-ecules, the CNB anion thereby coordinating in a bidentate O,O'-mode through the carboxyl-ate group. The latter, together with one water O atom and the N atom of the NA ligand, form a distorted square-planar arrangement, while the considerably distorted octa-hedral coordination sphere of the Zn(II) atom is completed by the two O atoms of additional water mol-ecules in the axial positions. The dihedral angles between the planar carboxyl-ate groups and the adjacent benzene rings in the two anions are 10.25 (10) and 5.89 (14)°. Inter-molecular O-H⋯O hydrogen bonds link two of the coordinating water mol-ecules to two free CNB anions. In the crystal, further hydrogen-bonding inter-actions are present, namely N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds that link the mol-ecular components, enclosing R 2 (2)(12), R 3 (3)(8) and R 3 (3)(9) ring motifs and forming layers parallel to (001). π-π contacts between benzene rings [centroid-to-centroid distances = 3.791 (1) and 3.882 (1) Å] may further stabilize the crystal structure.

Aqua-bis(4-methyl-benzoato)-κO;κO,O'-bis-(pyridine-κN)nickel(II).

Project description:In the title mononuclear complex, [Ni(C(8)H(7)O(2))(2)(C(5)H(5)N)(2)(H(2)O)], the Ni(II) atom is in a distorted octa-hedral arrangement, coordinated by three carboxylate O atoms from one bidentate 4-methyl-benzoate ligand and one monodentate 4-methyl-benzoate ligand, two N atoms from pyridine ligands, axially positioned, and a water mol-ecule. The equatorially positioned water mol-ecule and uncoordinated carb-oxylate O atom form an intra-molecular hydrogen bond. An inter-molecular O-H⋯O hydrogen bond between the coordinated water mol-ecule and carboxylate O atom of the 4-methyl-benzoate ligand forms infinite chains along the b axis. These chains are connected by C-H⋯π inter-actions.

catena-Poly[[aqua-(4-ethyl-benzoic acid-κO)lanthanum(III)]-tri-μ-4-ethyl-benzoato].

Project description:The reaction of lanthanum nitrate and 4-ethyl-benzoic acid (EBAH) in aqueous solution yielded the title polymer, [La(C(9)H(9)O(2))(3)(C(9)H(10)O(2))(H(2)O)](n). The asymmetric unit contains one La(III) atom, three 4-ethyl-benzoate (EBA) ligands, one neutral EBAH ligand and one coordinated water mol-ecule. Each La(III) ion is eight-coordinated by six O atoms from six bridging-bidentate EBA ligands, one O atom from a monodentate EBAH ligand and one water O atom in a distorted bicapped trigonal-prismatic geometry. The adjacent La(III) ions are linked by the carboxyl-ate groups of EBA ligands in a bridging-bidetate coordination mode, resulting in an infinite chain structure along the c axis. O-H⋯O hydrogen-bonding inter-actions involving the water mol-ecules, carboxyl-ate groups and carboxyl H atoms are formed within the one-dimensional polymer. One of the ethyl groups is disordered over two positions with occupancies of 0.717 (7) and 0.283 (7).

catena-Poly[[[aqua-silver(I)]-μ-4,4'-bipyridine-κN:N'] 4-amino-benzoate nitrate hydrate].

Project description:In the structure of the title compound, 2[Ag(C(10)H(8)N(2))(H(2)O)](C(7)H(6)NO(2))(NO(3))·H(2)O, the Ag(I) atom is three-coordinated in a T-shaped configuration by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) ligands at short distances and by one water O atom at a longer distance. Each bipy ligand bridges two neighbouring Ag(I) atoms, forming a chain structure extending parallel to [101]. The complete 4-amino-benzoate anion, the nitrate anion and the uncoordinated water mol-ecule are located on mirror planes: together with the coordinated water mol-ecule, they form N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, stabilizing the crystal structure.

Crystal structure of catena-poly[[[di-aqua-bis-(2,4,6-tri-methyl-benzoato-κO)cobalt(II)]-μ-aqua-κ2O:O] dihydrate].

Project description:The asymmetric unit of the title one-dimensional polymeric compound, {[Co(C10H11O2)2(H2O)3]·2H2O} n , contains one CoII cation situated on a centre of inversion, one-half of a coordinating water mol-ecule, one 2,4,6-tri-methyl-benzoate (TMB) anion together with one coordinating and one non-coordinating water mol-ecule; the TMB anion acts as a monodentate ligand. In the anion, the carboxyl-ate group is twisted away from the attached benzene ring by 84.9 (2)°. The CoII atom is coordinated by two TMB anions and two water mol-ecules in the basal plane, while another water mol-ecule bridges the CoII atoms in the axial directions, forming polymeric chains running along [001]. The coordination environment for the CoII cation is a slightly distorted octa-hedron. The coordinating and bridging water mol-ecules link to the carboxyl-ate groups via intra- and inter-molecular O-H⋯O hydrogen bonds, enclosing S(6) ring motifs, while the coordinating, bridging and non-coordinating water mol-ecules link to the carboxyl-ate groups and the coordinating water mol-ecules link to the non-coordinating water mol-ecules via O-H⋯O hydrogen bonds, enclosing R22(8) and R33(8) ring motifs. Weak C-H⋯O and C-H⋯π inter-actions may further stabilize the crystal structure.

catena-Poly[[(tri-phenyl-phosphane-?P)silver(I)]-?-4,4'-bi-pyridine-?(2) N:N'-[(tri-phenyl-phosphane-?P)silver(I)]-di-?-chlorido].

Project description:In the title coordination polymer, [Ag2Cl2(C10H8N2)(C18H15P)2] n , the Ag(I) cation is coordinated by a 4,4'-bi-pyridine N atom, a tri-phenyl-phosphane P atom and two Cl(-) anions in a distorted tetra-hedral geometry. The 4,4-bi-pyridine and Cl(-) anions bridge the Ag(I) cations, forming polymeric chains running along [21-1]. In the crystal, weak C-H?Cl inter-actions link the polymeric chains into a three-dimensiona supra-molecular architecture.

catena-Poly[[[tetra-aqua-nickel(II)]-?-4,4'-bipyridyl-?N:N'] 3,3'-(p-phenyl-ene)diacrylate].

Project description:In the title compound, {[Ni(C(10)H(8)N(2))(H(2)O)(4)](C(12)H(8)O(4))}(n), the Ni(II), 4,4'-bipyridyl (bipy) and 3,3'-(p-phenyl-ene)diacrylate (L(2-)) moieties are situated on inversion centres. The bipy ligands bridge Ni(II) ions into positively charged polymeric chains along [101]. The Ni(II) atom is coordinated by two N atoms from two bipy ligands and four water mol-ecules in a distorted octa-hedral geometry. L(2-) anions inter-act with the polymeric chains via O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

catena-Poly[[(tetra-aqua-cadmium)-?-4,4'-bipyridine-?(2)N:N'] 4-hy-droxy-3-sulfonato-benzoate monohydrate].

Project description:The two independent Cd(II) atoms in the polymeric title compound, [Cd(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(4)O(6)S)·H(2)O, lie on twofold rotation axes, and each is coordinated by four water mol-ecules and the N atoms of two 4,4'-bipyridine mol-ecules in an octa-hedral geometry. Bridging gives rise to chains along [101] and [-101]. The 4-hy-droxy-3-sulfonato-benzoate dianions are not connected to the Cd(II) atoms, but form hydrogen bonds to the coordinated water mol-ecules as well as the lattice water mol-ecule, generating a three-dimensional network.
