Synthesis and characterization of mono- and heterodinuclear complexes of dinucleating macrocyclic ligand bearing hexa- and pentadentate coordination sites
Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...

متن کاملOn Triggered Inversion in Hebrew
Triggered Inversion (TI) in Hebrew has been previously analyzed as canonical A'-movement to the specificer position of a functional projection in the CP-layer (Doron & Shlonsky 1990, Shlonsky 1997). This article examines the semantic properties of TI constructions in Hebrew, specifically the cross-linguistic similarities between TI in Hebrew and pseudoclefts (PC) in English, as discussed in Hey...
متن کاملSelf-assembly of heterodinuclear triple-stranded helicates: control by coordination number and charge.
Acylhydrazones of 2,3-dihydroxybenzaldehyde are easily accessible and afford heterodinuclear helicates; the self-assembly is specific when the resulting coordination compounds are neutral in charge.
متن کاملSynthesis, Crystal Structure and Properties of a Chiral 2D Zn(II) Coordination Polymer with Helical Chains
A chiral two-dimensional (2D) coordination polymer {[Zn(cmmb)(1,4-bbi)]·H2O}n (1) has been synthesized by a hydrothermal reaction of Zn(NO3)2·6H2O with 4(carboxymethoxy)-2-methylbenzoic acid (H2cmmb) and 1,1′-(1,4-butanediyl)bis(imidazole) (1,4-bbi). It has been characterized by elemental analysis, X-ray crystallography, IR spectroscopy and thermogravimetry, and also by its fluorescence propert...
