Catena-Poly[[(5-phenyl-2,2'-bipyridine-?N,N')copper(I)]-?-thio-cyanido-?N:S].

ABSTRACT: The title compound, [Cu(NCS)(C(16)H(12)N(2))](n), was synthesised under hydro-thermal conditions. The Cu(I) ion shows distorted tetra-hedral geometry being coordinated by two N atoms from a 5-phenyl-2,2'-bipyridine ligand and by the N and S atoms from two different thio-cyanate anions. The Cu(I) ions are bridged by thio-cyanide groups, forming a one-dimensional coordination polymer along the b axis. The crystal packing is through van der Waals contacts and C-H?? inter-actions.

Project description:The title compound, [Cu(2)(CN)(SCN)(C(10)H(8)N(2))(2)](n), contains two crystallographically independent Cu(I) atoms, each in a distorted tetra-hedral geometry. Each Cu atom is coordinated by a bidentate chelating 2,2'-bipyridine ligand. A bridging cyanide anion links the two Cu(2,2'-bipyridine) units to form a binuclear unit. Adjacent binuclear units are connected by a thio-cyanate anion into a one-dimensional helical chain along [010]. The cyanide anion is disordered, with each site occupied by both C and N atoms in an occupancy ratio of 0.61 (5):0.39 (5). The S atom of the thio-cyanate anion is also disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are π-π inter-actions between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) Å].

catena-Poly[{μ-cyanido-bis-[(4,4'-dimethyl-2,2'-bipyridine-κN,N')copper(I)]}-μ-cyanido-copper(I)-μ-cyanido].

Project description:In the title compound, [Cu(3)(CN)(3)(C(12)H(12)N(2))(2)], two 2,2'-bipyridine N,N'-chelated Cu(I) atoms are linked by a cyanide bridge that lies about a center of inversion; the Cu(I) atom exists in a tetra-hedral coordination geometry. This dinuclear entity is linked to another Cu(I) atom that lies on a twofold rotation axis by another cyanide bridge, these bridges giving rise to the formation of a linear chain motif.

Poly[penta-kis-(?-cyanido-?N:C)tris-(5-phenyl-2,2'-bipyridine-?N,N')penta-copper(I)].

Project description:The hydro-thermal reaction of Cu(acetate)(2) and K(3)[Fe(CN)(6)] with 5-phenyl-2,2'-bipyridine (5-ph-2,2'-bpy) in water yields the polymeric title complex, [Cu(5)(CN)(5)(C(16)H(12)N(2))(3)](n), which consists of ribbons along the a axis, constructed from 26-membered {Cu(10)(CN)(8)} rings. In these rings, the metal atoms are bridged by cyanide groups, except for one close Cu?Cu contact [2.7535?(12)?Å], which can be considered as ligand-unsupported. Within the rings, one Cu atom has a distorted tetra-hedral geometry through the coordination to two N atoms from 5-ph-2,2'-bpy and two N/C atoms from two cyanide groups. Two Cu atoms have a trigonal planar environment being coordinated by three cyanide groups and two other Cu atoms have a distorted square planar geometry through coordination to two N atoms from 5-ph-2,2'-bpy and two N/C atoms from two cyanide groups.

catena-Poly[[(2,2'-bipyridine)copper(II)]-μ-5-tert-butyl-isophthalato].

Project description:In the crystal structure of the title polymeric compound, [Cu(C(12)H(12)O(4))(C(10)H(8)N(2))](n), the asymmetric unit consists of one Cu(II) ion, one 5-tert-butyl-isophthalate (tbip) and one 2,2'-bipyridine (bpy) ligand. The copper(II) ion is four-coordin-ated by two N atoms from bipy and two O atoms from two tbip ligands, leading to a distorted tetrahedral coordination. Each tbip ligand adopts a bis-monodentate coordination mode to connect two symmetry-related copper(II) ions, so forming a zigzag polymer chain parallel to [001]. The tert-butyl methyl groups are disordered over two positions with occupancies of 0.506 (6)/0.494 (6).

catena-Poly[[(3-methyl-pyridine)-copper(I)]-?-cyanido-copper(I)-?-cyanido].

Project description:In the title complex, [Cu(2)(CN)(2)(C(6)H(7)N)](n), there are two copper atoms with different coordination environments. One Cu atom (Cu1) is linked to the two cyanide ligands, one N atom from a pyridine ring while the other (Cu2) is coordinated by the two cyanide ligands in a slightly distorted tetra-hedral geometry and linked to Cu1, forming a triangular coordination environment. The Cu atoms are bridged by bidentate cyanide ligands, forming an infinite Cu-CN chain. One cyanide ligand is equally disordered over two sets of sites, exchanging C and N atoms coordinated to both metal atoms. However, one cyanide group is not disordered and it coordinates to Cu1 via the N atom whereas its C-atom counterpart coordinates Cu2. The 3-methyl-pyridine (3MP) ligand coordinates through the N atom to Cu1 as a terminal ligand, which originates from decyanation of 3-pyridyl-acetonitrile under hydro-thermal conditions. Adjacent Cu-CN chains are inter-connected through Cu?Cu inter-actions [2.8364?(10)?Å], forming a three-dimensional framework.

catena-Poly[[aqua-(5,5'-dimethyl-2,2'-bipyridine-?N,N')copper(II)]-?-2,2'-oxydibenzoato-?O:O'].

Project description:In the title compound, [Cu(C(14)H(8)O(5))(C(12)H(12)N(2))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. Two N atoms of the chelating 5,5'-dimethyl-2,2'-bipyridine (dbp) ligand and two O atoms of two different 2,2'-oxydibenzoic (odb) ligands occupy the basal plane while the water O atom completes the square-pyramidal geometry at the apical site. The non-water N(2)O(2) donor atoms are nearly coplanar, with a mean deviation from the least-squares plane of 0.0518?(11)?Å and the Cu atom is displaced by 0.1507?(11)?Å from this plane towards the apical water O atom. Further coordination via the 2,2'-oxydibenzoate anions forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal structure, O-H?O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure.

catena-Poly[[[triaqua-copper(II)]-?-2,2'-bipyridine-3,3'-dicarboxyl-ato-?N,N':O] monohydrate].

Project description:The title compound, {[Cu(C(12)H(6)N(2)O(4))(H(2)O)(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The Cu(2+) ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2'-bipyridine-3,3'-dicarboxyl-ate bridging ligand in a sligthly distorted octa-hedral environment. The 2,2-bipyridine-3,3'-dicarboxyl-ate bridges link the Cu(2+) ions into chains along the b-axis direction. These chains are further linked by O-H?O hydrogen bonds involving the water solvent mol-ecules, forming a three-dimensional framework.

catena-Poly[[[(1,10-phenanthroline)copper(I)]-?-cyanido] ethanol hemisolvate].

Project description:In the title coordination polymer, {[Cu(CN)(C(12)H(10)N(2))]·0.5C(2)H(5)OH}(n), there are two Cu(I) ions, two 1,10-phenanthroline (phen) ligands and two cyanide ions in the asymmetric unit along with a highly disordered ethanol solvent mol-ecule, which was modelled as being disordered over two sets of sites in a 0.829?(7):0.171?(7) ratio. The orientation/ordering of the C and N atoms of the cyanide ions could not be determined in the present refinement and they were modelled as being statistically disordered. Both copper ions are coordinated by an N,N'-bidentate phen ligand and two cyanide ligands, generating distorted tetra-hedral CuN(2)Q(2) (Q = C or N) tetra-hedra. The ?-cyanide ligands link the metal ions, forming a zigzag chain propagating in [001]. The chains are cross-linked by numerous aromatic ?-? stacking contacts between adjacent phen rings [minimum centroid-centroid separation = 3.620?(3)?Å].

catena-Poly[[aqua-(2,2'-bipyridine-κN,N')copper(II)]-μ-5-nitro-isophthalato-κO,O:O].

Project description:In the asymmetric unit of the title compound, [Cu(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)](n), there are two symmetry-independent one-dimensional coordination polymers related by a non-crystallographic inversion center. Within the polymers, the Cu(II )atoms, coordinated by the water mol-ecule and the chelating 2,2'-bipyridine ligands, are bridged by 5-nitro-benzene-1,3-dicarboxyl-ate dianions which act as tridentate ligands; the carboxyl-ate groups exhibit monodentate and symmetric bidentate coordination modes. The Cu(II) atoms show a strongly distorted octa-hedral coordination geometry. In the crystal structure, the two symmetry-independent coordination polymers form another one-dimensional polymeric structure via O-H⋯O hydrogen bonds between coordinated water mol-ecules and carboxyl-ate groups.

catena-Poly[[(2,2'-bipyridine)-manganese(II)]-?(3)-4,4'-sulfonyl-dibenzoato].

Project description:In the title compound, [Mn(C(14)H(8)O(6)S)(C(10)H(8)N(2))](n), the Mn(II) ion is coordinated by four O atoms from three 4,4'-sulfonyl-dibenzoate (sdba) ligands and two N atoms from one 2,2'-bipyridine (2,2'-bipy) ligand in a distorted octa-hedral geometry. The manganese atoms are alternately bridged either by two sdba ligands, with an Mn?Mn separation of 12.284?(1)?Å, or by two carboxyl-ate groups from two sdba ligands, with an Mn?Mn separation of 4.064?(1)?Å, thus producing polymeric chains propagated in [101]. Weak inter-molecular C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance of 3.730?(3)?Å between the aromatic rings of neighbouring polymeric chains] further stabilize the crystal packing.
