The title compound, [La(C(7)H(3)O(6)S)(H(2)O)](n), forms a three-dimensional framework in which the asymmetric unit contains one La(III) atom, one 5-sulfosalicylate (2-oxido-4-sulfonatobenzoate) ligand and one coordinated water mol-ecule. The La(III) atom is coordinated by nine O atoms from three carboxyl-ate, three sulfonate and two hydroxyl groups, and one water mol-ecule, forming a distorted...

The title oxidovanadium(V) complex, [V(C(15)H(11)N(3)O(5))(CH(3)O)O], was obtained by the reaction of 2-hy-droxy-3-meth-oxy-benzaldehyde, 4-nitro-benzohydrazide and vanadyl sulfate in methanol. The V(V) atom is five-coordinated by the two O and one N donor atoms of the Schiff base ligand, one methano-late O atom and one oxido O atom, forming a distorted square-pyramidal geometry.

In the title compound, [Ni(C(17)H(17)FN(3)O(3))(2)](n), the Ni(II) atom exists in a distorted trans-NiN(2)O(4) octa-hedral geometry defined by two monodentate N-bonded and two bidentate O,O-bonded 1-cyclo-propyl-6-fluoro-4-oxido-7-(1-piperazin-yl)-1,4-dihydro-quinoline-3-carboxyl-ate (ciprofloxacinium) monoanions. The extended two-dimensional structure is a square grid. The Ni atom lies on a ce...

In the title coordination polymer, [Zn(C(14)H(11)NO(3))(C(2)H(6)OS)](n), each Zn(II) ion is five-coordinated in a slightly distorted trigonal-bipyramidal coordination environment, formed by three O atoms from two 2-[(2-oxido-1-naphth-yl)-methyl-eneamino]propanoate ligands, one O atom from a dimethyl sulfoxide mol-ecule and the N atom from the amino-propanoate ligand. The propanoate ligands brid...

Treatment of Bi(2)O(3) with the acids; S-(+)-10-camphorsulfonic, 2,4,6-mesitylenesulfonic and sulfamic, under sonication at room temperature in water for 2-4 h, results in the formation and subsequent crystallisation of polynuclear bismuth oxido-clusters; [Bi(18)O(12)(OH)(12)(O(3)S-Cam)(18)(H(2)O)(2)], [Bi(38)O(45)(O(3)S-Mes)(24)(H(2)O)(14)] and [Bi(6)O(4)(OH)(4)(O(3)SNH(2))(6)].
