Synthesis, Structure, Biological Activity, and Luminescence Properties of a "Butterfly"-Type Silver Cluster with 3-Benzyl-4-phenyl-1,2,4-triazol-5-thiol.

A new silver(I) cluster [AgL(Py)(Pype)]·4Py·11HO () with 3-benzyl-4-phenyl-1,2,4-triazol-5-thiol (L) was synthesized via the direct reaction of AgNO and L in MeOH, followed by recrystallization from a pyridine-piperidine mixture. The compound was isolated in a monocrystal form and its crystal structure was determined via single crystal X-ray diffraction. The complex forms a "butterfly" cluster with triazol-5-thioles.

α-Diimine Cisplatin Derivatives: Synthesis, Structure, Cyclic Voltammetry and Cytotoxicity.

Three new Pt(II) complexes [(dpp-DAD)PtCl] (), [(Mes-DAD(Me))PtCl] () and [(dpp-DAD(Me))PtCl] () were synthesized by the direct reaction of [(CHCN)PtCl] and corresponding redox-active 1,4-diaza-1,3-butadienes (DAD). The compounds were isolated in a single crystal form and their molecular structures were determined by X-ray diffraction. The purity of the complexes and their stability in solution was confirmed by NMR analysis.

What are the prospects for using complexes of copper(ii) and zinc(ii) to suppress the vital activity of ?

New complexes of zinc(ii) and copper(ii) with 2-furoic acid (Hfur), acetic acids and N-donor ligands with the compositions [Zn(fur)] (1), [Zn(fur)(NHpy)] (2, NHpy = 3-aminopyridine), [Zn(fur)(neoc)] (3, neoc = 2,9-dimethyl-1,10-phenantroline), [Zn(OAc)(neoc)] (4, OAc = acetat-anion), and [Cu(fur)(neoc)(HO)] (5) were synthesized. The structures of the compounds were established by single crystal X-ray diffraction analysis. Complexes 1 and 2 are binuclear; whereas 3-5 are mononuclear.

A new heterometallic pivalate {FeCd} complex as an example of unusual "ferric wheel" molecular self-assembly.

The interaction of the pivalate complexes of iron(iii), [Fe3O(Piv)6(H2O)3]·HPiv, and cadmium(ii), [Cd(Piv)2], in Et2O resulted in one more type of "ferric wheel" family complex, namely [Fe8(Piv)16{Cd(Piv)2}(μ-OH)8]·Et2O (1). The complex is an octanuclear iron(iii) wheel with a {Cd(Piv)2} moiety asymmetrically incorporated into the ring.
