The synthesis of ferroeene-ethynyl phosphine platinum dichloride complexes based on (FeC=C)"Ph3 _ nP (ta, 11 = 1; tb, 11 = 2; te, 11 = 3; Fe = ferroeenyl, (.,s-CsHs)(.,s-CsH4 )Fe) is deseribed. Air-oxidation of te afforded (FeC= ChP=O (6). Treatment of ta-tc with [(PhC= NJ,PtClz] (2) or [(tht)AuCI] (tht = tetrahydrothiophene) (7), respeetively, gave the(More)
We herein describe a systematic account of mononuclear ruthenium vinyl complexes L-{Ru}-CH=CH-R where the phosphine ligands at the (PR'3)2Ru(CO)Cl={Ru} moiety, the coordination number at the metal (L = 4-ethylisonicotinate or a vacant coordination site) and the substituent R (R = nbutyl, phenyl, 1-pyrenyl) have been varied. Structures of the enynyl complex(More)
Trinuclear ferrocene tris-amides were synthesized from an Fmoc- or Boc-protected ferrocene amino acid, and hydrogen-bonded zigzag conformations were determined by NMR spectroscopy, molecular modelling, and X-ray diffraction. In these ordered secondary structures orientation of the individual amide dipole moments approximately in the same direction results(More)
Radically complex: The photolytic reaction of [Cp*P{W(CO)(5)}(2)] (Cp* = C(5)Me(5)) with a diphosphene produces, via a radical intermediate, an air-stable complexed triphosphaallyl radical, in which the unpaired electron is evenly distributed over both terminal P atoms. Oxidation of the radical leads to a triphosphaallyl cation, which is only stable at low(More)
Regio- and stereoselective insertion of the terminal ethynyl functions of 4-ethynylstilbene, the E and Z isomers of 4,4'-bis(ethynylphenyl)ethene and a backbone-rigidified cyclohexenyl derivative of the Z isomer into the Ru-H bond of the complex RuClH(CO)(P(i)Pr(3))(2) provides the corresponding vinyl ruthenium complexes, which have been characterized(More)
A straightforward synthesis methodology for the preparation of heterobimetallic [(lls-CsHs)(lls-CsH4CSMe4)Mj (3a, M = Fe; 3b, M = Ru) and [(lls-CsHs)((j.1-lls:11s-CsH4-CsMe4)TiCl3)Mj (4a, M = Fe; 4b. M = Ru) in which early and late transition metals are connected by a fulvalenediyl bridge is reported.
A series of highly unsymmetric heterobinuclear Mn/Co complexes is reported, in which an organometallic CpMn(CO)z fragment and a classical Werner-type cobalt(II) subunit are arranged in close proximity by means of a bridging pyrazolate. Two ligand scaffolds are employed that differ by the chelate size of the tripodal tetradentate {N41 binding site for(More)
The ability of the easily reducible tetracyanoethylene (TCNE) ligand to bridge up to four metal centers and to adopt any oxidation state between 0 and -2 has generated a unique coordination chemistry with potential applications in molecular magnetism, electrochromism, and molecular computing. The coordination chemistry of electroactive,(More)
Cyclic oligomers comprising strongly interacting redox-active monomer units represent an unknown, yet highly desirable class of nanoscale materials. Here we describe the synthesis and properties of the first family of molecules belonging to this compound category-differently sized rings comprising only 1,1'-disubstituted ferrocene units (cyclo[n], n = 5-7,(More)
We report on the platinum complexes trans-Pt(BODIPY)(8-ethynyl-BODIPY)(PEt3)2 (EtBPtB) and trans-Pt(BODIPY)(4-ethynyl-1,8-naphthalimide)(PR3)2 (R = Et, EtNIPtB-1; R = Ph, EtNIPtB-2), which all contain two different dye ligands that are connected to the platinum atom by a direct σ bond. The molecular structures of all complexes were established by X-ray(More)
