Following our interest in binary element–nitrogen compounds we report here on the synthesis and comprehensive characterization (M.p., IR/Raman, elemental analysis, 14N/133Cd/199Hg NMR) of tri‐ and tetraazido cadmate and mercurate anions [E(N3)(2+n)]n− (E=Cd, Hg; n=1, 2) in a series of [Ph4P]+ and [PNP]+ ([PNP]+=bis(triphenylphosphine)iminium) salts. The azide/chloride exchange in CH2Cl2 as well as

salts of the monosubstituted hexanuclear anions [Ir6(CO)14X]–[X = Cl (1), Br (2), I (3), or SCN (4)] have been prepared by treating [Ir6(CO)16] with halides or pseudohalides at room temperature in tetrahydrofuran solution. Complex (2) crystallizes in the monoclinic space group P21/c(no. 14) with a= 12.653(4), b= 25.566(10), c= 13.351(2)Å, β= 91.04(2)°, and Z= 4, (3) crystallizes in the monoclinic space

The mobility of Cu+, Ag+, In+, and Tl+ in halide compounds has been investigated to develop an understanding of the factors which are important in fast ion conduction. Many of the compounds in the comparison are of the type MM′X4, where M is one of the monopositive ions listed above, M′ is Zn2+, Cd2+, or Hg2+, and X is Br− or I−. These compounds are characterized by transitions at elevated temperatures
Advances in the Reactivity of Amido-Bridged Binuclear Carbonylruthenium Complexes – Derivative Chemistry of the Cationic Complex [Ru2(μ-dan)(μ-H)(CO)6][BF4] (H2dan = 1,8-Diaminonaphthalene)

The reactivity of the cationic amido-bridged binuclear transformed into the asymmetric isomer 7b under thermal conditions (70 °C, 10 h) or under acid catalysis ([HOEt2][BF4], ruthenium carbonyl complex [Ru2(μ-dan)(μ-H)(CO)6] (H2dan = 1,8-diaminonaphthalene) (2) with some anionic and 18 °C, 1 min). Such isomerization reactions can be prevented by adding an excess of triphenylphoshane to the solutions

complexes have the formula (PPN)(Os/sub3/(CO)/sub 10/(..mu..-CH/sub 2/)(..mu..-X)). PPN-(triphenylphosphine)/sub 2/N/sup +/; X = Cl, Br, I, or NCO. These complexes react in less than 1 min to form the ketene clusters. Such a reaction without the halide ligand requires 4 h to go to completion. The most interesting finding of the study is the accelerating effect of the X ligands. 15 references, 2 figures
