Novel zinc complexes with acetyloacetonate, imidazole and thiolate ligands: Crystal structure of a zinc complex of relevance to farnesyl transferase
PublicationOtrzymano dwa nowe kompleksy cynku z ligandami S-,N- i O-donorowymi i scharakteryzowano je za pomocą rentgenowskiej analizy strukturalnej i spektroskopii w podczerwieni. Jeden z tych kompleksów jest pierwszym kompleksem modelującym centrum aktywne transferazy farnezylu.

Structural analysis and physico-chemical characterization of mononuclear manganese(II) and polynuclear copper(II) complexes with pyridine-based alcohol
PublicationTwo novel manganese(II) and copper(II) complexes, mononuclear [Mn(H2O)2(2-(CH2)2OHpy)2](NO3)2 (1) and polynuclear [Cu(SO4)(2-(CH2)2OHpy)2]n (2), based on 2-(hydroxyethyl)pyridine (2-(CH2)2OHpy) were synthesised and fully characterised using X-ray structure analysis as well as spectroscopic, magnetic and thermal methods. Both central metal ions Mn(1) and Cu(1) are coordinated by two N,O-donor 2-(CH2)2OHpy ligands and possess an...

General route for the synthesis of terminal phosphanylphosphido complexes of Zr(IV) and Hf(IV): Structural investigations of the first zirconium complex with a phosphanylphosphido ligand
PublicationReactions of R2P-P(SiMe3)Li with [Cp2MCl2] (M = Zr, Hf) in hydrocarbons yield the related terminal phosphanylphosphidocomplexes [Cp2M(Cl){(Me3Si)P-PR2-jP1}] (R = iPr and tBu). The solid state structures of [Cp2M(Cl){P(SiMe3)-PiPr2-jP1}] (M = Zr, Hf) were established by single crystal X-ray diffraction studies. The phosphido-P atoms adopt almost planar geometries and the phosphanyl P atoms adopt pyramidal geometries. The reaction...

Phosphoroorganic Metal Complexes in Therapeutics
PublicationThe present mini-review highlights recent developments on antitumor activity of metal-based therapeutics which have been a subject of researches for the last few decades. In 1965, Rosenberg found that during an electrolysis on platinum electrodes a complex of Pt is generated which inhibited to a great extent a binary fission in Escherichia coli bacteria. This discovery started a new chapter in medicinal chemistry and the interesting...

Thiolate complexes of molybdenum. synthesis and application
PublicationZwiązki molibdenu, w tym siarczki, posiadają własności katalityczne i są szeroko wykorzystywane m.in. w przemyśle petrochemicznym. Enzym nitrogenaza posiadający w centrum aktywnym molibdenu umożliwia reakcję redukcji azotu atmosferycznego w niskiej temperaturze i pod ciśnieniem atmosferycznym. Ta sama reakcja w przemyśle wymaga zastosowania znacznie bardziej drastycznych warunków. Stąd wieloletnie zainteresowanie badaczy możliwością...
