In the title compound, [Ag(C(14)H(10)N(4)O)(2)]CF(3)SO(3), two N atoms from two independent pyridyl rings of two N'-3-cyano-benzyl-ideneisonicotinohydrazide ligands coordinate to the unique Ag(I) ion, forming a nearly linear coordination geometry. Adjacent silver complexes are primarily linked together by Ag⋯N inter-actions, with Ag⋯N separations of 2.877 (2) and 3.314 (2) Å. On the other hand,...

Three new dinitrosyl iron complexes LFe(NO)(2) (L = 2,2'-bipyridine (bipy) (1), 2,2',2''-terpyridine (terpy) (2) and 1,10-phenathroline (phen) (3)) were synthesized by the reaction of Fe(NO)(2)(CO)(2) with corresponding ligands in tetrahydrofuran. Complexes 1-3 were studied using IR, UV-vis, MS, NMR, and electrochemical techniques. Complexes 1 and 2 were also characterized using single crystal ...

The synthesis of the symmetric pyrazine imide ligand, N-(2-pyrazylcarbonyl)-2-pyrazinecarboxamide, (Hdpzca) and five new first row transition metal complexes of it are reported: [M(II)(dpzca)(2)], M(II) = Fe, Cu, Zn; [Cu(II)(dpzca)(H(2)O)(2)]BF(4), [Cu(II)(dpzca)(H(2)O)(3)](2)SiF(6). The crystal structures of Hdpzca, [Co(II)(dpzca)(2)], [Cu(II)(dpzca)(2)], {[Co(III)(dpzca)(2)](BF(4))}(2)·5CH(3)...

Reactions of Cd(NO(3))(2)·4H(2)O with TabHPF(6) (TabH = 4-(trimethylammonio)benzenethiol) and Et(3)N in the presence of NH(4)SCN and five other N-donor ligands such as 2,2'-bipyridine (2,2'-bipy), phenanthroline (phen), 2,9-dimethyl-1,10-phenanthroline (2,9-dmphen), 2,6-bis(pyrazd-3-yl)pyridine (bppy) and 2,6-bis(3,5-dimethyl-1H-pyrazol-1-yl)pyridine (bdmppy) gave rise to a family of Cd(II)/thi...

Metal/N-heterocyclic carbene (NHC) complexes hold great opportunities for the development of novel antitumor metallodrugs. Herein, four Ag(I) and Au(I) complexes containing NHCs derived from cyclophanes have been prepared and characterized as potential anticancer agents. These complexes show higher cytotoxicity than cisplatin against several cancer cell lines including a cisplatin-resistant cel...

The hydro-thermal reaction of butane-1,2,3,4-tetra-carboxylic acid (H(4)butca), 4,4'-bipyridine (bipy) and Mn(SO(4))(2)·H(2)O afforded a new co-crystal, C(8)H(10)O(8)·2C(10)H(8)N(2) or H(4)butca·2(bipy), in which strong O-H⋯N hydrogen-bonding and weak π-π stacking [centroid-centroid distance = 3.8459 (19) Å] inter-actions assemble the organic mol-ecules into a three-dimensional supra-molecular ...

A relevant series of symmetric supramolecular porphyrins has been obtained by attaching four [RuII(bipy)2Cl] groups to the pyridyl substituents of meso-tetra(4-pyridyl)porphyrin and its metallated derivatives. These compounds display a rich electrochemistry and versatile catalytic, electrocatalytic and photochemical properties, associated with the ruthenium-bipyridine and the porphyrin complexe...

New cationic Ag(I) complexes were prepared by reaction of AgBF4 with two thioether-functionalized bis(diphenylphosphino)amine ligands, Ph2PN(p-ArSMe)PPh2 (L1) and Ph2PN(n-PrSMe)PPh2 (L2), and compared with those obtained from the unfunctionalized ligands Ph2PN(Ph)PPh2 (L3) and Ph2PN(n-Bu)PPh2 (L4), respectively. The complex [Ag3(μ3-Cl)2(μ2-L1-P,P)3](BF4) (1·BF4) contains a triangular array of A...
