Emerging contaminants in the environment have caused enormous concern in the last few decades, and among them, antibiotics have received special attention. On the other hand, adsorption has shown to be a useful, low-cost, and eco-friendly method for the removal of this type of contaminants from water. This work is focused on the study of ciprofloxacin (CPX) removal from water by adsorption on p...

The monomeric title zirconium(IV) compound, [Zr(C(12)H(21)N(2)Si)(2)Cl(2)], was prepared by the metathetical reaction of [LiN(SiMe(2)NMe(2))(2,6-Me(2)C(6)H(3))](2) with zirconium tetra-chloride. The Zr(IV) atom is N,N'-chelated by the N-silylated anilido ligand. Along with two Cl atoms, the six-coordinated Zr(IV) atom demonstrates a highly distorted octa-hedral geometry. The two ligands around ...

Two alkyl and aryl substituted five-membered zirconacycloallenoids underwent a typical σ-alkyl metallocene reaction with B(C6F5)3, namely cleavage of the Zr-C(sp(3)) bond with formation of zwitterionic (η(2)-allenyl)zirconium/alkylborate products. Both products were characterized by X-ray crystal structural analyses.
