The Sn atom in the polymeric title compound, [Sn(C(6)H(5))(3)(C(10)H(16)NO(3))](n), is five-coordinated within a trans-C(3)O(2) donor set that defines an approximate trigonal-bipyramidal geometry. The carboxyl-ate ligand is monodentate and the amide O atom bridges a symmetry-related Sn atom, generating a chain along [010] with a linear topology. An intra-molecular carboxyl-ate-carbonyl N-H⋯O hydrogen bond is responsible for the curved conformation within the carboxyl-ate ligand.

The asymmetric unit of the title compound, [Co(CBrO)(CHN)(HO)] or [Co(Brbdc)(im)(HO)] , comprises half of Co ion, tetra-bromo-benzene-dicarboxylate (Brbdc), imidazole (im) and a water mol-ecule. The Co ion exhibits a six-coordinated octa-hedral geometry with two oxygen atoms of the Brbdc ligand, two oxygen atoms of the water mol-ecules, and two nitro-gen atoms of the im ligands. The carboxyl-ate group is nearly perpendicular to the benzene ring and shows monodentate coordination to the Co ion.

Crystals of the title salt, (CHN)[Sn(CH)(CHOS)], comprise diisobutyl-ammonium cations and mercapto-acetato-tri-phenyl-stannate(IV) anions. The bidentate binding mode of the mercapto-acetate ligand gives rise to a five-coordinated, ionic tri-phenyl-tin complex with a distorted -trigonal-bipyramidal geometry around the tin atom. In the crystal, charge-assisted ammonium-N-H⋯O(carboxyl-ate) hydrogen-bonding connects two cations and two anions into a four-ion aggregate.

The title compound, (CHN)[(CHNO)(MoO)]·4HO, which crystallizes in the monoclinic 2/ space group, was obtained by mixing molybdenum oxide, ethyl-enedi-amine and ethyl-enedi-amine-tetra-acetic acid (Hedta) in a 2:4:1 ratio. The complex anion contains two MoO units bridged by an edta anion. The midpoint of the central C-C bond of the edta anion is located on a crystallographic inversion centre.

In the title complex, [U(CHNO)O(CHOH)] , the U cation has a typical penta-gonal-bipyramidal environment with the equatorial plane defined by one N and two O atoms of one doubly deprotonated 2-[5-(2-hy-droxy-phen-yl)-1-1,2,4-triazol-3-yl]acetic acid ligand, a carboxyl-ate O atom of the symmetry-related ligand and the O atom of the methanol mol-ecule [U-N/O 2.256 (4)-2.504 (5) Å].
