New polymeric ligand (resin) was prepared by the condensation of thiosemicarbazides with formaldehyde in the presence of acidic medium. Thisemicarbazide-formaldehyde polymer-metal complexes were prepared with Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) in 1 : 2 metal : ligand molar ratio. The polymeric ligand and its polymer-metal complexes were characterized by elemental analysis, thermogravimetric analysis (TGA), FTIR, 13C NMR and 1H NMR. The geometry of central metal ions was conformed by electronic (UV-vis) and EPR spectra. The antibacterial activities of all the synthesized polymers were investigated against Bacillus subtilis and Staphylococcus aureus (Gram-positive) and Escherichia coli and Salmonella typhi (Gram-negative). These compounds showed excellent activities against these bacteria using the shaking flask method.

With the aid of multifunctional ultrasonic irradiation, maleic anhydride can be grafted onto CB at ambient temperature in a relatively short time. The attached anhydride ring can be hydrolyzed to two carboxylic groups. These groups can be further utilized to tailor the surface properties of CB.

New original water magnetic fluids containing iron oxide magnetic nanoparticles based on natural components: magnetite - oleic acid - biologically active silyl modified alkanolamine have been obtained. Magnetic properties, concentration of magnetite and size of iron oxide core of the nanoparticles synthesized have been carried out. Magnetic fluids possess low or moderate cytotoxic effects concerning human fibrosarcoma, mouse hepatoma monolayer tumour cell lines, are non-toxic, exhibit high NO-induction ability and strongly change tumour cell morphology.

Synthesis, crystal structure and infrared spectra of Cu(II) and Co(II) complexes with 4,4prime-dichloro-2,2prime-[ethylene dioxybis(nitrilomethylidyne)]diphenol (p 89-96)

4,4-dichloro-2,2-[ethylenedioxybis(nitrilomethylidyne)]diphenol (H2L), and its complexes [CuL] and ([CoL(THF)]2(OAc)2Co have been synthesized and characterized by elemental analyses, IR, 1H-NMR and X-ray crystallography. [CuL] forms a mononuclear structure which may be stabilized by the intermolecular contacts between copper(II) atom and oxygen atom (O3) to form a head-to-tail dimer. In [CoL(THF)]2(OAc)2Co, two acetates coordinate to three cobalt(II) atoms through Co-O-C-O-Co bridges and four µ-phenoxo oxygen atoms from two [CoL(THF)] units also coordinate to cobalt(II) atoms.

Fe-MCM-41 was successfully synthesized the via sol-gel technique using silatrane and FeCl3 as the silicon and iron sources. The catalytic activity and selectivity of styrene epoxidation using hydrogen peroxide showed that the selectivity of the styrene oxide reached 65% at a styrene conversion of 22% over the 1%wt catalyst.

Diorganotin(IV) complexes R2Sn(LH)2 (R = Me, nBu) and {[nBu2Sn(LH)]2O}2 (LH = 4-[(2Z)-(3-hydroxy-1-methyl-2-butenylidene)amino]benzoate and 4-[{(E)-1-(2-hydroxyphenyl)methylidene} amino] benzoate) have been reported. The complexes were characterized by elemental analysis, IR, NMR (1H, 13C, 119Sn) and 119mSn Mössbauer spectroscopy. Crystal structures of a ligand {HO2CC6H4[NC(H)}{C(CH3)CH(CH3)- 3 - OH]- p} and one of its di-n-butyltin(IV) complexes (nBu2Sn{O2CC6H4[NC(H)}{C(CH3)CH(CH3)- 3 - OH]- p}2) were determined.

The toxicity of ferrocenylethyl benzotriazole and other ferrocene-containing benzimidazole and adenine derivatives was evaluated. All ferrocene compounds under investigation showed low or middle toxicities. The antitumor activity of ferrocenylalkyl azoles and ferricenium salts was studied in vivo in the so-called sub-capsular test on human tumors. A series of ferrocenylalkyl azoles were synthesized. The X-ray determinations of -(1-benzotriazolyl)ethylferrocene and -(1-naphthatriazolyl)ethylferrocene were performed.
