BACKGROUND The anticancer properties of cisplatin and palladium(II) complexes stem from the ability of the cis-MCl2 fragment to bind to DNA bases. However, cisplatin also interacts with non-cancer cells, mainly through bonding molecules containing -SH groups, resulting in nephrotoxicity. This has aroused interest in the design of palladium(II) complexes of improved activity and lower toxicity. ...

In the title one-dimensional coordination polymer, {[ZnCl(2)(C(18)H(14)N(4))]·0.25H(2)O}(n), the Zn(II) atom is coordinated by two chloride ions and two 4,4'-bis-(1H-imidazol-1-yl)biphenyl ligands, generating a distorted tetra-hedral ZnCl(2)N(2) geometry. The dihedral angle between the benzene rings of the ligand is 51.0 (1)° and the dihedral angles between the benzene rings and their attached ...

The title compound, {[Ag(C(19)H(16)N(8))](CF(3)SO(3))}(n), is a coordin-ation polymer with cationic chain motif. The Ag(+) cation is coordinated by two unsubstituted imidazolyl N atoms of two independent 2-paBIM ligands [2-paBIM is bis-{2-[(E)-phenyl-diazen-yl]-1H-imidazol-1-yl}methane]. The shortest Ag⋯Ag separation in a cationic chain is 8.841 (2) Å and the dihedral angle between two 2-phenyl...

A chiral two-dimensional (2D) coordination polymer {[Zn(cmmb)(1,4-bbi)]·H2O}n (1) has been synthesized by a hydrothermal reaction of Zn(NO3)2·6H2O with 4(carboxymethoxy)-2-methylbenzoic acid (H2cmmb) and 1,1′-(1,4-butanediyl)bis(imidazole) (1,4-bbi). It has been characterized by elemental analysis, X-ray crystallography, IR spectroscopy and thermogravimetry, and also by its fluorescence propert...

A self-assembly reaction between the ditopic ligand 4,5-bis(tetrazol-5-yl)imidazole (H3IBT) and cobalt(II) chloride in basic aqueous medium afforded the mixed-valence molecular species ðNBu4Þ141⁄2Co III 6Co II 2ðIBTÞ12 22H2O (1). X-ray analysis of 1 revealed a cubic arrangement of six trivalent and two divalent cobalt ions, with the latter situated on opposing vertices along the cube diagonal. ...
