catena-Poly[sodium [[tris(3-methyl­pyridine-2-carboxylato)europate(III)]-μ-3-methylpyridine-2-carboxylato] trihydrate]

In the title structure, {Na[Eu(C(7)H(6)NO(2))(4)]·3H(2)O}(n), the Eu(III) atom is nine-coordin-ated within a slightly distorted tricapped trigonal-prismatic coordination geometry defined by five carboxyl-ate-O atoms and four pyridine-N atoms. One of the carboxyl-ate ligands bridges the Eu cations, forming a one-dimensional coordination polymer along the b axis. The Eu-O bond distances lie withi...

The Crystal Structure of Monoaquabis(trans-5- -methylpyrazine-2-carboxylato-N,O)copper(II) Trihydrate

catena-Poly[[diaquaterbium(III)]-tetrakis(μ2-pyridine-4-carboxylato-κ2 O:O′)-[diaquaterbium(III)]-bis(μ2-pyridine-4-carboxylato-κ2 O:O′)]

The title complex, [Tb(2)(C(6)H(4)NO(2))(6)(H(2)O)(4)](n), was isolated under hydro-thermal conditions using the ligand pyridine-4-carb-oxy-lic acid (HL) and Tb(2)O(3). The deprotonated L(2-) ligands adopt bridging coordination modes. The central Tb(III) atom is bridged by L(2-) ligands, forming a polymeric chain parallel to the a axis. Supra-molecular O-H⋯N inter-actions link the chains, build...

Anticancer activities of the ruthenium carboxylato, amido and pyridine complexes.

Ruthenium complexes [1-3] with oxalato, amido and pyridine ligands have been synthesized and characterized. Biological tests showed that the ruthenium complexes 2 and 3 have modest cytotoxicity on both murine cell line NIH3T3 and human cancer colon cell lines HCT116 and HT29 while complex 1 has no obvious growth defect. We further tested why complexes 2 and 3 exhibit modest cytotoxicity. Gel el...

Syntheses, crystal structures and magnetic properties of a series of μ-phenoxo-μ1,1-carboxylato-μ1,3-carboxylato trinickel(II) compounds.

The work in this report describes the syntheses, characterization, crystal structures and magnetic properties of eight linear trinickel(ii) compounds of the composition [Ni(II)3(L(sal-pyr))2(propionate)4] (), [Ni(II)3(L(sal-pyr))2(benzoate)4]·CH3CN (), [Ni(II)3(L(sal-pip))2(acetate)4]·2CH3CN (), [Ni(II)3(L(sal-pip))2(propionate)4] (), [Ni(II)3(L(sal-pip))2(benzoate)4]·CH2Cl2 (), [Ni(II)3(L(sal-...
