The complexes of Cu(i) and Ag(i) with 1,3,5-triaza-7-phosphadamantane (PTA) are currently studied for their potential clinical use as anticancer agents, given the cytotoxicity they exhibited in vitro towards a panel of several human tumor cell lines. These metallodrugs are prepared in the form of [M(PTA)4]+ (M = Cu+, Ag+) compounds and dissolved in physiological solution for their administratio...

The purpose of this study was to prepare high oxidation-state rhenium oxomethyl complexes, including cationic compounds, and test selected examples for olefin polymerization activity. Reaction of ReOMe2(PMe3)2Cl with pyridine N-oxide and 2,2 -bipyridine (bipy) gave cis-ReOMe2(bipy)Cl. Conversely, treatment of ReO(bipy)Cl3 with AlMe3 gave trans-ReOMe2(bipy)Cl. The compound cis-ReOMe2(bipy)Cl iso...

The following gold(I) and silver(I) complexes of the tritertiary phosphine 1,1,1- tris(diphenylphosphinomethyl)ethane, tripod , have been synthesised: Au(3)(tripod)X(3) [X = Cl(1), Br(2), I(3)]; [Au(3)(tripod)(2)Cl(2)]Cl (4); Au(tripod)X [X = Br(5), I(6)]; Ag(3)(tripod) (NO(3))(4) (7), Ag(tripod)NO(3) (8). They were characterized by X-ray diffraction (complexes 2, 3 and 4), (31)P NMR spectrosco...

A series of transition metal complexes with two thiosemicarbazide Schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (ABTSC) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (TCTS) were synthesized with Co(II), Ni(II), Zn(II), Cd(II) and Ag(I) salts (chloride and acetate). These complexes were characterized by different methods including proton nuclear magnetic resonance (1HNMR),...

1,1-Diamino-2,2-dinitroethene (FOX-7) reacts readily with copper nitrate in an aqueous solution of potassium hydroxide to form pea green Cu(FOX)(2)(H(2)O)(2) (5). FOX-7 complexes of copper and nickel supported by a variety of diamines including Cu(en)(2)(FOX)(2)(H(2)O) (1), Cu(pn)(2)(FOX)(2) (2), Cu(bipy)(FOX)(2)(H(2)O)(4) (3a), Cu(bipy)(2)(FOX)(2)(H(2)O)(2.5) (3b), Cu(bipy)(FOX)(2)(DMSO)(2)·2D...

A series of Zn(II) and Cd(II) complexes with a flexible dicarboxylate building block and various heterocyclic co-ligands, formulated as {[Zn(2)(pda)(2)(phen)(2)].2H(2)O}(n) (1), {[Zn(pda)(dpe)].H(2)O}(n) (2), [Zn(pda)(bpp)](n) (3), {[Cd(2)(pda)(2)(2,2'-bipy)(2)].2H(2)O}(n) (4), {[Cd(pda)(4,4'-bipy)(H(2)O)].H(2)O}(n) (5) and {[Cd(2)(pda)(2)(bpp)(3)].14H(2)O}(n) (6) (pda = 1,3-phenylenediacetate,...

Mild deprotonation of a 2-pyridyl (py)-functionalized phosphoric triamide [PO(NHpy)(3)] in the absence of an external base was studied in the presence of various silver(I) salts. Interesting examples of octa- and hepta-nuclear Ag(I) complexes coordinated to imido and pyridyl groups were obtained when more reactive Ag(I) salts, such as AgClO(4) and AgBF(4), were used, while the less reactive AgN...
