The preparation and characterization of the new 3,5-diacetyl-1,2,4-triazol bis(4-cyclohexyl thiosemicarbazone) ligand, H(5)L(1), is described. Treatment of H(5)L(1) with K(2)PtCl(4) gave the dinuclear complex [Pt(H(3)L(1))](2), 1, but using MCl(2)(PPh(3))(2) where M = Pd or Pt, mononuclear complexes 2 and 3, of general formula [M(H(3)L(1))PPh(3)], were obtained. Subsequent reaction of the [Pd(H...

Platinum bis-amidine complexes (both the cis and trans isomers) are stable in acetone and chlorinated solvents but are unstable in protic solvents such as methanol or water. In the latter solvents an initial cis/trans isomerization leads to formation of an equilibrium mixture with a cis/trans ratio of about 1:4; subsequently a dinuclear platinum(III) complex (1) is formed under aerobic conditio...

The Cover Feature shows that 1-butene molecules can penetrate into a dense crystalline solid and drive the transformation of planar trinuclear fluorinated copper(I) pyrazolate complexes toward boat-shaped, dinuclear copper-butene adducts. chemistry these with is also examined in solution, comparison analogous adducts formed ethene propene provided. More information be found Full Paper by M. G. ...

Cationic tetranuclear arene ruthenium complexes of the general formula [Ru4(p-cymene)4(N N)2(dhnq)2] comprising rectangular structures are obtained in methanol from the reaction of the dinuclear arene ruthenium precursor [Ru2(p-cymene)2(dhnq)2Cl2] (dhnq = 5,8-dihydroxy-1,4-naphthoquinonato) with pyrazine or bipyridine linkers [N N = pyrazine, 1; 4,4 -bipyridine, 2; 1,2-bis(4-pyridyl)ethylene, 3...

There have been reported suitably designed, simple monoand dinuclear metal complexes which are efficient in hydrolyzing phosphate esters including DNA. We have previously reported the dinuclear Cu(II)2L1 complex (L1: 1,3-bis(1,4,7triaza-1-cyclononyl)propane) efficiently hydrolyzed DNA, producing nicked and linearized DNA over the mononuclear CuL2 complex (L2: 1,4,7-triazacyclononane). We were i...

Copper(II) acetate mediated coupling reactions between 2,6-bis(azidomethyl)pyridine or 2-picolylazide and two terminal alkynes afford 1,2,3-triazolyl-containing ligands L(1)-L(6). These ligands contain various nitrogen-based Lewis basic sites including two different pyridyls, two nitrogen atoms on a 1,2,3-triazolyl ring, and the azido group. A rich structural diversity, which includes mononucle...

Substitution of the halide ligands in (Bu4N)2[Mo3S7X6] (X = Cl, Br) by diimine ligands, such as 4,4'-dimethyl-2,2'-bipyridine (dmbpy), 2,2'-bipyridine (bpy) and 1,10-phenanthroline (phen), affords the neutral heteroleptic clusters Mo3S7Cl4(dmbpy) (), Mo3S7Br4(dmbpy) (), Mo3S7Br4(bpy) (), and Mo3S7Br4(phen) (). Further substitution of the halide ligands in Mo3S7Br4(diimine) clusters by dmit (1,3...

Dinuclear rhenium(I) complexes having a fac-[Re(CO)3](+) moiety of general formula fac-[Re2(CO)6(hq)2] have been synthesized in excellent yield by reacting [Re(CO)5Cl] with Hhq in a ratio of 1 : 1 in toluene in an argon atmosphere. Here hq(-) is the deprotonated form of 5-phenylazo-8-hydroxyquinoline (Hhq(1)), 5-(2-naphthylazo)-8-hydroxyquinoline (Hhq(2)) and 5-(2-fluorineazo)-8-hydroxyquinolin...
