Reaction of a trinuclear iron(II) complex, Fe3 Br3 L (1), with KC8 under N2 leads to dinitrogen activation products (2) from which Fe3 (NH)3 L (2-1; L is a cyclophane bridged by three β-diketiminate arms) was characterized by X-ray crystallography. (1) H NMR spectra of the protonolysis product of 2 synthesized under (14) N2 and (15) N2 confirm atmospheric N2 reduction, and ammonia is detected b...

The complete molecule of the title compound, [Cu2(C2H3O2)2(CF3O3S)2(C12H8N2)2], is completed by the application of a twofold rotation and comprises two Cu(II) ions, each of which is penta-coordinated by two N atoms from a bidentate 1,10-phenanthroline (phen) ligand, two O atoms from acetate ligands and an O atom from a tri-fluoro-methane-sulfonate anion, forming a (4 + 1) distorted square-pyram...

In the title compound, [RuCl(C18H15P)(C26H31N2OP)](CF3O3S)·2C3H6O, the Ru(II) ion is coordinated in a three-legged piano stool, half-sandwich-type geometry by a chlorido ligand, a tri-phenyl-phosphine and a tethered η(6)-(phenyl-p-O-meth-oxy) κ(1)-P N-di-phenyl-phosphino N'-diisopropyl amidine ligand charge-balanced by a trifluormethansulfonate counter-anion. The η(6)-coordination mode of the a...

Liquid ammonia, trialkyl phosphites, and especially trialkylphosphines, are very powerful electron-pair donor solvents with soft bonding character. The solvent molecules act as strongly coordinating ligands towards mercury(ii), interacting strongly enough to displace halide ligands. In liquid ammonia mercury(ii) chloride solutions separate into two liquid phases; the upper contains tetraamminem...

The conformationally restricted adenine nucleotide analogs 8,3'anhydro-8-oxy-9-(beta-D-xylofuranosyl)adenine-5'-O-tri(di)-phosphate (I), and 8,2'-anhydro-8-oxy-9-(beta-D-arabinofuranosyl) adenine-5'-O-tri(di)-phosphate (II), were prepared chemically as their alpha-32P-labelled compounds and compared with syn-structured 8-bromo AT(D)P in mitochondrial adenine nucleotide translocation. The experi...
