Poly[[tris-(?(2)-4,4'-bipyridine N,N'-di-oxide)hexa-nitratodigadolinium(III)] dichloro-methane disolvate].

ABSTRACT: The title one-dimensional coordination network, {[Gd(2)(NO(3))(6)(C(10)H(8)N(2)O(2))(3)]·2CH(2)Cl(2)}(n), is isostructural with the previously reported Tb and Tl coordination networks and to its Eu analog. The Gd(III) cation is coordinated in a distorted tricapped trigonal-prismatic fashion by nine O atoms from three bridging 4,4'-bipyridine N,N'-dioxide ligands and three chelating nitrate anions. None of the atoms lie on a special position, but there is an inversion center located between the rings of one of the ligands. The network topology is ladder-like, and each ladder inter-acts with six neighboring ladders through C-H?O hydrogen bonds. The packing motif of the ladders allows for the formation of channels that run parallel to the a axis; these channels are filled with CH(2)Cl(2) solvent mol-ecules that inter-act with the ladders through C-H?O hydrogen bonds.

catena-Poly[[[tetra-aqua-cobalt(II)]-?-4,4'-bipyridine-?N:N'] bis-(perchlorate) 4,4'-bipyridine disolvate dihydrate].

Project description:In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.

4,4'-Bipyridine acetic acid disolvate.

Project description:The crystal structure of the title compound, C(10)H(8)N(2)·2C(2)H(4)O(2), is built up from 4,4'-bipyridine and acetic acid mol-ecules linked by strong O-H?N hydrogen bonds. The 4,4'-bipyridine and the two acetic acid mol-ecules are further connected through weak C-H?O hydrogen bonds to form a supra-molecular two-dimensional network parallel to the (001) plane. The two pyridine rings make a dihedral angle of 31.8?(1)°.

Poly[diaqua-bis(2,2'-bipyridine)tris-(?(4)-2,2'-bipyridine-4,4'-dicarboxyl-ato)dineodymium(III)].

Project description:In the crystal structure of the title mixed-ligand coordination polymer, [Nd(2)(C(12)H(6)N(2)O(4))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)](n), the Nd(III) ion is in an octa-hedral coordination environment formed by one water mol-ecule, one chelating 2,2'-bipyridine ligand, and five monodentate carboxyl-ate groups. The local coordination polyhedron around the Nd(III) ion is a bicapped trigonal prism. Two Nd(III) centers are bridged by four carboxyl-ate groups to form an Nd(2) dimeric unit; these are further connected by 2,2'-bipyridine-4,4'-dicarboxyl-ate linkers, resulting in a layered coordination network.

Project description:In the title compound, {[Co(C(8)H(4)O(4))(C(10)H(8)N(2)O(2))(H(2)O)(2)]·C(10)H(8)N(2)O(2)}(n), the Co(II) atom, lying on an inversion center, is hexa-coordinated in a distorted octa-hedral geometry defined by two O atoms from two terephthalate (tp) ligands, two O atoms from two 4,4'-bipyridine N,N'-dioxide (bpydo) ligands and two water mol-ecules. The coordinated tp and bpydo ligands and uncoordinated bpydo mol-ecule all have an inversion center. The Co(II) atoms are connected by the tp and bpydo ligands into a layer parallel to (111). In the crystal, O-H?O hydrogen bonds link the uncoordinated bpydo mol-ecules and the layers into a three-dimensional supra-molecular structure. Intra-layer O-H?O hydrogen bonds and ?-? inter-actions [centroid-to-centroid distances = 3.6643?(13) and 3.8048?(13)?Å] are also observed.

Poly[bis-(4,4'-bipyridine)(μ(3)-4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ato)iron(II)].

Project description:In the polymeric title complex, [Fe(C(16)H(8)O(8))(C(10)H(8)N(2))(2)](n), the iron(II) cation is coordinated by four O atoms from three different 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands and two N atoms from two 4,4'-bipyridine ligands in a distorted octa-hedral geometry. The 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands bridge adjacent cations, forming chains parallel to the c axis. The chains are further connected by inter-molecular O-H⋯N hydrogen bonds, forming two-dimensional supra-molecular layers parallel to (010).

Tris(4,4'-di-tert-butyl-2,2'-bipyridine-?N,N')molybdenum(II) ?(6)-oxido-dodeca-?(2)-oxido-hexa-oxidohexa-molybdate(VI) acetonitrile tetra-solvate.

Project description:The asymmetric unit of the title compound, [Mo(C(18)H(24)N(2))(3)][Mo(6)O(19)]·4CH(3)CN, comprises an [Mo(di-t-Bu-bipy)(3)](2+) cation (di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine), two halves of Lindqvist-type [Mo(6)O(19)](2-) anions (with each anion completed by the application of a center of inversion) and four acetonitrile solvent mol-ecules. The geometry around the metal atom of the cation resembles a distorted octa-hedron, with each of the three di-t-Bu-bipy ligands being almost planar [deviation from planarity < 6.3?(2)°]. Supra-molecular inter-actions, namely Mo=O??, C N??, C-H?O and C-H?N, along with electrostatic forces, mediate the crystal packing. Two of the tert-butyl groups are affected by rotational disorder which was modeled over two distinct positions with major site occupancies of 0.707?(9) and 0.769?(8).

Poly[[bis-(?(2)-4,4'-bipyridine)[?(2)-(2,4-dichloro-phen-oxy)acetato]copper(I)] nitrate].

Project description:The title compound, {[Cu(2)(C(8)H(5)Cl(2)O(3))(C(10)H(8)N(2))(2)]NO(3)}(n) was prepared by reacting copper(II) nitrate with 4,4'-bipyridine (4,4'-bipy) and (2,4-dichloro-phen-oxy)acetic acid under solvothermal conditions. Each of two copper(I) atoms in the asymmetric unit is three-coordinated by two N atoms from two 4,4'-bipy ligands and one O atom from the (2,4-dichloro-phen-oxy)acetate ligand. As both ligands act as bridging ligands, a double-stranded chain structure is observed.

catena-Poly[[(4,4'-dimethyl-2,2'-bipyridine-?(2) N,N')cadmium]-di-?-bromido].

Project description:In the crystal of the title polymeric compound, [CdBr2(C12H12N2)] n , the Cd(II) cation is located on a twofold rotation axis and is six-coordinated in a distorted octa-hedral geometry formed by two N atoms from the 4,4'-dimethyl-2,2'-bipyridine ligand and by four bridging Br(-) anions. The bridging function of the Br(-) anions leads to a polymeric chain running along the c axis. Weak C-H?? inter-actions observed between adjacent chains are effective in the stabilization of the three-dimensional packing.
