Pd(II) and Pt(II) complexes of formulae [MLCl2], where L = mepirizole, were synthesized and characterized. Two complexes were obtained and studied by different techniques: IR, 1H and 13C NMR and XPS spectroscopies and mass spectrometry (electrospray). The crystal structure of the complex cis-dichloro-4-methoxy-2-(5-methoxy-3-methyl-(More)
The reaction of di-2-pyridyl ketone, (2-py)2CO, with Ni(O2CMe)(2).4H2O yields the cage [Ni9(OH)2(O2CMe)8((2-py)2CO2)4], which reacts further with N3- ions to give the structurally similar cluster [Ni9(N3)2(O2CMe)8((2-py)2CO2)4] containing extremely rare eta 1,mu 4-N3- groups; magnetic studies reveal that the spin ground state of the latter is nine times the(More)
Four new metal complexes {M = Pd(II) or Pt(II)} containing the ligand 9-aminoacridine (9AA) were prepared. The compounds were characterized by FT-IR and (1)H, (13)C, and (195)Pt NMR spectroscopies. Crystal structure of the palladium complex of formulae [Pd(9AA)(mu-Cl)](2) . 2DMF was determined by X-ray diffraction. Two 9-acridine molecules in the imine form(More)
The synthesis of P,P'-dimesityl-P,P'-diphenyldiphosphine and benzylmesitylphenylphosphine is described as well as the resolution of the latter ligand by means of homochiral organometallic complexes. The absolute configuration of the phosphine is assigned by NMR spectra, using the homochiral palladacycle as a reference point. The configuration has been(More)
We report here the X-ray structure of cytotoxic trans-¿PtCl(2)(dimethylamine)(isopropylamine). This trans-platinum compound crystallizes in the monoclinic system, with Z = 8, in the spatial group C2/c with unit cell parameters a = 19.862(17) A, b = 6. 581(3) A, c = 18.563(3) A, alpha = 90 degrees, beta = 119.16(3) degrees, gamma = 90 degrees, V = 2119(2)(More)
The synthesis and chemical characterization of two trans platinum complexes, (1) trans-[PtCl(2)NH(3)(2-hydroxymethylpyridine)] and (2) trans-[PtCl(2)NH(3)(3-hydroxymethylpyridine)], are described. The structures and chemical behaviour of these compounds have been compared to those of their isomer (3) trans-[PtCl(2)NH(3)(4-hydroxymethylpyridine)] previously(More)
rac-[Co(ambi)3]Cl3.3H2O corresponds to a tris-chelate complex bearing 2-(aminomethyl)benzimidazole (ambi) ligands bound to the Co(III) ion in a facial-type fashion. The high metal q/r ratio and electronic delocalization between coordination heterocyclic functionalities can provide powerful tools to minimize DNA condensation, which arises from the(More)
The crystal and molecular structure of the sodium salt of deoxycytidylyl-(3H-5H)-deoxyguanosine has been determined from X-ray diffraction data. The crystal, obtained from an aqueous gamma-butyrolactone solution at pH = 5.3 are orthorhombic, P212121, a = 10.640(2), b = 11.184(2) and c = 44.618(4)A. The structure was refined to an R = 0.041. The d(CpG)(More)
The new compound trimethylene-N(6),N(6')-bisadenine (L), in which two adenine molecules are linked together by a trimethylene bridge that connects the N(6) atoms, has been prepared. Reaction of L with HgCl(2) and ZnCl(2) in concentrated HCl solution leads to crystalline solids. The X-ray characterisation of the Hg(II) complex (H(2)L)[HgCl(4)].3H(2)O reveals(More)
