Catena-Poly[[dipyridine-cadmium(II)]-?-5-amino-2,4,6-triiodo-isophthalato].

ABSTRACT: The hydro-thermal reaction of cadmium(II) nitrate with 5-amino-2,4,6-triiodo-isophthalic acid and pyridine in DMF solution leads to the formation of the title compound, [Cd(C(8)H(2)I(3)NO(4))(C(5)H(5)N)(2)](n). The structure contains a four-coordinate Cd(2+ )ion in a distorted tetra-hedral geometry, which lies on a crystallographic twofold rotation axis. The Cd(2+ )ion is bonded to two N atoms from two pyridine ligands and two carboxyl-ate O atoms from two 5-amino-2,4,6-triiodo-isophthalate anions. The Cd-O distances are 2.429?(5) and 2.305?(5)?Å and the Cd-N distance is 2.236?(8)?Å. The two carboxyl-ate groups of individual 5-amino-2,4,6-triiodo-isophthalate anions act as a bridge to the Cd(2+) atoms. leading to a chain structure along the c axis.

catena-Poly[[aqua-dipyridine-copper(II)]-μ-fumarato].

Project description:The title compound, [Cu(C(4)H(2)O(4))(C(5)H(5)N)(2)(H(2)O)](n), is a one-dimensional coordination polymer based on pyridine and fumarate ligands. Each Cu(II) cation is coordinated by two carboxyl-ate O atoms belonging to two fumarate anions, two N atoms from two pyridine mol-ecules and one water mol-ecule, in a square-based pyramidal geometry. Each fumarate anion bridges two Cu(II) cations through the two carboxyl-ate groups in a bis-monodentate fashion to form a one-dimensional polymeric chain along the c axis. Neighbouring chains are linked together to form a two-dimensional network parallel to the ac plane via hydrogen bonding inter-actions between uncoordinated carboxyl-ate O atoms and coordinated water mol-ecules of adjecent chains.

catena-Poly[[tripyridine-nickel(II)]-?-5-bromo-isophthalato].

Project description:The title compound, [Ni(C(8)H(3)BrO(4))(C(5)H(5)N)(3)], is the first structurally characterized complex with a transition metal coordinated by a 5-bromo-isophthalate anion. The Ni(II) ion is coordinated by three O atoms from the carboxyl-ate groups and three N atoms from three pyridine ligands in a distorted octa-hedral coordination geometry. The 5-bromo-isophthalate anion is planar within 0.057?(2)?Å. The two carboxyl-ate groups of the ligand coordinate the Ni(II) ions in a chelating and monodentate mode, linking the metal atoms into infinite chains along the [010] direction. These chains are stacked together via strong ?-? inter-actions between the pyridine rings [centroid-centroid distance 3.601?(4)?Å], forming a three-dimensional motif.

Project description:The title compound, [Cd(C(8)H(4)O(5))(H(2)O)(3)](n), a one-dimensional chain complex of 5-hy-droxy-isophthalate with Cd(II), was prepared by a hydro-thermal reaction.

Dimethyl 5-amino-2,4,6-triiodo-isophthalate.

Project description:The title compound, C(10)H(8)I(3)NO(4), crystallizes with two mol-ecules in the asymmetric unit. The I atoms and the benzene ring plane in the two mol-ecules are approximately coplanar, the I atoms deviating by -0.1631?(1), 0.0704?(1) and -0.0507?(1)?Å from the mean plane of the benzene ring in one mol-ecule and by 0.1500?(1), -0.0034?(1) and -0.1213?(1)?Å in the other. The planes of the ester groups are almost orthogonal to those of the benzene rings in both mol-ecules, forming dihedral angles of 83.5?(3), 76.4?(3), 97.3?(1) and 75.7?(1)°. The mean planes of the benzene rings in two mol-ecules are inclined at 69.8?(3)° with respect to each other. In the crystal, inter-molecular I?O inter-actions link the mol-ecules into infinite chains. In addition, N-H?O and non-classical C-H?O hydrogen bonds are observed.

Poly[tetra-?-cyanido-dipyridine-cadmium(II)zinc(II)].

Project description:In the title coordination polymer, [CdZn(CN)(4)(C(5)H(5)N)(2)](n), the Zn(II) atom (site symmetry 222) adopts a distorted ZnC(4) tetra-hedral geometry, being coordinated by four crystallographically equivalent cyanide ions. The cyanide ion bridges to a Cd(II) centre via its N atom. The Cd atom (site symmetry 2/m) coordination is a distorted CdN(6) octa-hedron, arising from four cyanide N atoms and two pyridine N atoms. The complete pyridine mol-ecule is generated by m symmetry, with the N atom and one C atom lying on the reflecting plane. In the crystal, the bridging cyanide ions result in a three-dimensional network.

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[[(1,10-phenanthroline)manganese(II)]-μ(3)-5-methyl-isophthalato].

Project description:In the title coupound, [Mn(C(9)H(6)O(4))(C(12)H(8)N(2))](n), the Mn(II) ion is coordinated by two N atoms [Mn-N = 2.273 (3) and 2.305 (2) Å] from a 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.112 (2)-2.343 (3) Å] from three 5-methyl-isophthalate (mip) ligands in a distorted octa-hedral geometry. Each mip dianion acts as a tetra-dentate ligand connecting three Mn ions. The crystal packing exhibits π-π inter-actions [3.599 (2)-3.755 (2) Å] between the centroids of the six-membered rings of neighbouring 1,10-phenanthroline ligands.

catena-Poly[[aqua-(2,2'-bipyridyl)cobalt(II)]-μ-5-nitro-isophthalato].

Project description:In the crystal structure of the title compound, [Co(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, which are approximately related by noncrystallographic inversion symmetry. Each zigzag chain is constructed from one Co(II) ion, one O-monodentate 5-nitro-isophthalate (ndc) dianion, one N,N'-bidentate 2,2'-bipyridyl ligand and one water mol-ecule. A symmetry-generated O,O'-bidentate ndc dianion completes the cobalt coordination environment, which could be described as very distorted cis-CoN(2)O(4) octa-hedral. The bridging ndc ligands result in parallel chains running along the a direction, and O-H⋯O hydrogen bonds arising from the water mol-ecules complete the structure.
