In the title mononuclear complex, [Ni(C(8)H(7)O(2))(2)(C(5)H(5)N)(2)(H(2)O)], the Ni(II) atom is in a distorted octa-hedral arrangement, coordinated by three carboxylate O atoms from one bidentate 4-methyl-benzoate ligand and one monodentate 4-methyl-benzoate ligand, two N atoms from pyridine ligands, axially positioned, and a water mol-ecule. The equatorially positioned water mol-ecule and unc...

The methyl 3-amino-6-bromothieno[3,2-b]pyridine-2-carboxylate, recently reported by some of us, was reacted in Sonogashira couplings with several (hetero)arylacetylenes. The growth inhibitory activity of the novel methyl 3-amino-6-[(hetero)arylethynyl]thieno[3,2-b]pyridine-2-carboxylates obtained was evaluated on three human tumor cell lines (MCF-7, NCI-H460, A375-C5). The para-methoxyphenyl an...

The title solvated molecular salt, C(4)H(12)N(2) (2+)·C(7)H(3)NO(4) (2-)·CH(3)OH or (pipzH(2))(py-2,3-dc)·MeOH, was prepared by the reaction of pyridine-2,3-dicarb-oxy-lic acid (py-2,3-dcH(2)) and piperazine (pipz) in methanol (MeOH) as solvent. One of the two carboxylate groups of the acid fragment is nearly perpendicular to the pyridine ring and the other is almost in its plane [C-C-C-O torsi...

The reaction of mercury(II) chloride with 5-amino-2,4,6-triiodo-isophthalic acid in pyridine solution leads to the formation of the title compound, [Hg(C(8)H(2)I(3)NO(4))(C(5)H(5)N)(2)](n). The structure contains a four-coordinate Hg(2+) ion in a distorted tetra-hedral geometry, which lies on a crystallographic twofold axis. The Hg(2+) ion is bonded to two N atoms from two pyridine ligands and ...
