In the crystal structure of the title compound, [Zn(C(6)H(2)O(5))(H(2)O)(3)](n), an infinite chain is formed along [001] by linking of the Zn(H(2)O)(3) entities with one carboxyl-ate group of the furan-2,5-dicarboxyl-ate ligand. Adjacent chains are linked by O(water)-H⋯O hydrogen-bonding inter-actions. The Zn(H(2)O)(3)O(3) polyhedron displays a distorted octa-hedral geometry with one weak Zn-O(...

In the crystal structure of the title compound, [Zn(C(6)H(2)O(5))(CH(3)OH)(2)(H(2)O)](n), an infinite chain is formed along the b axis by linking of the Zn(OH(2))(CH(3)OH)(2) unit with one carboxyl-ate group of the furan-2,5-dicarboxyl-ate ligand. The Zn(II) ion is in a distorted octa-hedral environment with one weak coordination [Zn-O(carboxyl-ate) = 2.565 (3) Å] and two meth-anol mol-ecules l...

In the title complex, [Pr(2)(C(2)O(4))(3)(H(2)O)(4)](n), the two independent Pr(III) ions are both nine-coordinated in a distorted monocapped square-anti-prismatic geometry by seven O atoms from four oxalate ligands and two water mol-ecules. The Pr(III) ions are bridged by the oxalate ligands, forming a layer parallel to (001). O-H⋯O hydrogen bonds connect the layers.
متن کاملBiologic activities of poly (2-azaadenylic acid) and poly (2-azainosinic acid).
Poly (2-azaadenylic acid) [(aza2A)n] and poly(2-azainosinic acid [(aza2I)n], two newly synthesized analogues of (A)n and (I)n, in which CH-2 of the purine ring is replaced by a nitrogen atom, have been evaluated in various biological assay systems. (Aza2A) n formed a complex with (U)n and (br5U)n, and (aza2I)n formed a complex with (C)n and (br5C)n, but these complexes were markedly destabilize...

In the title compound, [CaCs2(C2O4)2(H2O)4] n , the Ca(2+) ion, lying on a twofold rotation axis, is coordinated by four O atoms from two oxalate ligands and two bridging water mol-ecules in an octa-hedral geometry. The Cs(+) ion is coordinated by seven O atoms from six oxalate ligands, one bridging water and one terminal water mol-ecule. The oxalate ligand displays a scarce high denticity. The...
