Self-flux-grown BaFeClO crystals exhibiting structures with tunable modulation.

The synthesis and X-ray structural study of the new family of compounds BaFeClO with tunable structural modulation are reported. The framework of the structure has the BaFeO composition, with open hexagonal channels extending along the -axis. The channels are filled with linear [Ba-Cl-Ba] triplets.

[Restoration of erectile function by reconstructing cavernous nerves with small intestinal submucosa grafts].

Objective: To investigate the restoration of erectile function by reconstructing cavernous nerves (CN) with small intestinal submucosa (SIS) grafts.

Methods: We prepared SIS grafts, established rat models and divided the models into a CN ablation, a sham-operation and an SIS graft group. The CNs at both sides were severed with 1 cm ablated in the first group, and 0.

Lanthanide coordination polymers constructed from infinite rod-shaped secondary building units and flexible ligands.

Three lanthanide coordination polymers constructed from infinite rod-shaped secondary building units (SBUs), [Nd(2)(H(2)O)(2)(cis-chdc)(2)(trans-chdc)]2H(2)O (1), Nd(2)(H(2)O)(4)(trans-chdc)(3) (2), and [Sm(2)(H(2)O)(2)(cis-chdc)(trans-chdc)(2)]4H(2)O (3) (chdcH(2)=1,4-cyclohexanedicarboxylic acid), were hydrothermally synthesized and structurally characterized. The structures of 1-3 are modulated by different ratios of the cis and trans configurations of chdc(2-) ligands, which was achieved by temperature control in the hydrothermal reactions. Crystal-structure analysis revealed that 1 is a four-connected pcu-type rod packing network built from cross-linking of rod-shaped neodymium-oxygen SBUs by cis- and trans-chdc(2-) ligands in a 2:1 ratio, 2 displays a complicated six-connected hex-type rod packing structure built by connection of rod-shaped neodymium-oxygen SBUs and trans-chdc(2-) ligands, and 3 features an unprecedented five-connected rod packing pattern constructed from rod-shaped samarium-oxygen SBUs and cis- and trans-chdc(2-) ligands in a 1:2 ratio.

A new chain-like cadmium(II) coordination polymer containing chains of water molecules.

The title cadmium(II) polymer, catena-poly[[[bis(4-aminopyridine-kappaN)aquacadmium(II)]-mu-1,4-phenylenediacetato-kappa(4)O,O':O'',O'''] dihydrate], {[Cd(C10H8O4)(C5H6N2)2(H2O)].2H2O}n, comprises one-dimensional wave-like chains, in which the Cd atom is coordinated by 1,4-phenylenediacetate and 4-aminopyridine molecules. The 1,4-phenylenediacetate ligands lie about inversion centres.

A novel three-dimensional supramolecular coordination polymer: poly[[diaquadicadmium(II)-di-mu2-4,4'-bipyridyl-di-mu2-2-sulfonatobenzoato] dihydrate].

The hydrothermal reaction of Cd(CH3COO)2.2H2O, 4,4'-bipyridyl and 2-sulfobenzoic acid produced the title compound, {[Cd2(C7H4O5S)2(C10H8N2)2(H2O)2].2H2O}n, which forms a two-dimensional coordination polymer, the sheets of which are linked via hydrogen bonds.

trans-Diaquabis(5-carboxy-1H-imidazole-4-carboxylato-kappa2N3,O4)cobalt(II) 4,4'-bipyridine solvate.

In the title compound, [Co(C(5)H(3)N(2)O(4))(2)(H(2)O)(2)].C(10)H(8)N(2), the Co atom is trans-coordinated by two pairs of N and O atoms from two monoanionic 4,5-dicarboxyimidazole ligands, and by two O atoms from two coordinated water molecules, in a distorted octahedral geometry. The 4,4'-bipyridine solvent molecule is not involved in coordination but is linked by an N-H.
