Transition Metal Carbide Complexes
Chemical Reviews, 2021Carbide complexes remain a rare class of molecules. Their paucity does not reflect exceptional instability but is rather due to the generally narrow scope of synthetic procedures for constructing carbide complexes. The preparation of carbide complexes typically revolves around generating LnM-CEx fragments, followed by cleavage of the C-E bonds of the ...

Journal of Medicinal Chemistry, 1986
The preparation of stable complexes between the N7-[2-(2-pyridyl)ethyl] and N7-(2-piperazinylethyl) derivatives of mitomycin C and metal ions such as Cu(II), Zn(II), and Pt(II) was accomplished. Mitomycin C did not form stable complexes, but it rearranged to a mitosene capable of complex formation. Some of these complexes had antitumor activity in mice.

Metal Complexes of Dithiatetrazocines
Phosphorus, Sulfur, and Silicon and the Related Elements, 1992Abstract Dithiatetrazocines of the type 1,5-E2N4S2 (E=Me2NC, R2P) form the transition metal complexes M(PR3)2(1,5-E2N4S2) (M=Pt, Pd, Ni) which involve an η2- S, S′ interaction with the metal. A reversible elimination of R3P from these mononuclear complexes gives the binuclear complexes [M(PR3)(1,5-E2N4S2)]2.

Zeolite Encapsulated Metal Complexes
Journal of inclusion phenomena and molecular recognition in chemistry, 1995The potential for coupling the shape selectivity associated with the well-defined channels and cages of zeolites with the reactivity of metal complexes makes these molecular sieves particularly attractive as solid supports. Zeolites have a distinct advantage over conventional support materials in that a metal complex can be physically trapped in the ...

Complexation Parameters of Terpyridine-Metal Complexes
2006Terpyridine ligands were used for the construction of model complexes, which were characterized by NMR, UV-vis and MALDI-TOF mass spectrometry. Subsequently, the kinetics of the complex formation was investigated by isothermal titration microcalorimetry (ITC) to obtain the complexation constants. In addition, the complexation reaction was studied by UV-

Transition metal borylene complexes
Chemical Society Reviews, 2013Borylene ligands (:BR) are isolobal to CO and other iconic organometallic ligands. As such, borylene ligands enjoy some parallels to these ligands, but in many ways, their chemistry is distinct. This tutorial review gives an introduction to the synthesis, properties and reactivity of the major classes of transition metal borylene complexes, including ...

Metal–organic complex ferroelectrics
Chemical Society Reviews, 2011Ferroelectric materials are of importance and interest in both fundamental scientific research and various technological applications. Metal-organic complexes (MOCs) represent a class of molecule-based ferroelectrics, which have shown various properties or functionalities due to their hybrid inorganic-organic nature.

Catalyzed Complex Metal Hydrides
MRS Bulletin, 2002AbstractComplex hydrides are mixed ionic–covalent compounds that can serve as reversible H2storage media only when they are catalyzed by a transition metal such as Ti. As the prime example, the phenomenology of Ti-catalyzed sodium alanate (NaAlH4) is reviewed from a historical perspective.

Polysulfide Complexes of Metals
1987Publisher Summary Sulfide minerals were formed mostly hydrothermally from postmagnetic fluids; it appears remarkable that the formation of many ore deposits cannot be conclusively explained because of the very low solubility of the corresponding sulfide.
