The interaction of guanine, guanosine or 5 0-GMP (guanosine 5 0-monophosphate) with [Pd(en)(H 2 O) 2 ](NO 3) 2 and [Pd(dapol)(H 2 O) 2 ](NO 3) 2 , where en is ethylenediamine and dapol is 2-hydroxy-1,3-propanediamine, were studied by UV–Vis, pH titration and 1 H NMR. The pH titration data show that both N1 and N7 can coordinate to [Pd(en)(H 2 O) 2 ] 2þ or(More)
The Pd(II) atom in the complex cation of the title compound, [PdCl(C(21)H(16)N(4))]Cl, is coordinated by three N atoms derived from the terpyridine ligand and a chloride ion, which define a distorted PdClN(3) square-planar coordination geometry. In the crystal, the presence of N-H⋯Cl hydrogen bonds involving the amino H atom and chloride anions link two(More)
The title compound, [PdCl 2 (C 6 H 16 N 3)](C 7 H 7 SO 3), consists of a Pd II atom bonded to two N atoms of the 1,4,7-triazacyclo-nonane (TACN) ligand and two chloride ions, which define a distorted square-planar geometry. The third N atom of the TACN ligand is protonated and hydrogen bonds to the p-toluenesulfonate anion. The Cl—Pd—Cl angle is larger than(More)
The title salt, [Pd(C(6)H(4)N(2))(4)](CF(3)SO(3))(2), comprises Pd(4-cyano-pyridine)(4) dications balanced by two trifluoro-methane-sulfonate anions. The Pd(II) atom lies in a square-planar geometry defined by four N atoms which form equivalent Pd-N inter-actions. The 4-cyano-pyridine ligands are twisted out of the N(4) plane, forming dihedral angles(More)
