Trinuclear Cu (II)-complexes of formula [Cu (II) 3(mu 3-E)(mu-4-R-pz) 3X 3] (+/- n ), E = O and OH; R = H, Cl, Br, CH(O) and NO 2; X = Cl, NCS, CH 3COO, and py, have been synthesized and characterized and the effect of substitution of terminal ligands, as well as 4-R-groups, in the one-electron oxidation process has been investigated by cyclic voltammetry.… (More)
Upon crystallization in high yields, metallacrowns form compartments that are capable of asymmetrically encapsulating three isonicotinate guests.
Rare blue-colored pseudorotaxanes based on the previously unexplored [N,N'-bis(4-pyridyl)-4,4'-bipyridinium](2+) axle and bis(1,5-naphtho)-32-crown-8 (BN32C8) or bis(1,5-naphtho)-38-crown-10 (BN38C10) wheels have been synthesized and characterized by UV-vis, (1)H NMR spectroscopy, and electrochemistry, and their metal-binding properties toward CdI(2) and… (More)
The reaction of amines with aldehydes and ketones has been exploited for over 150 years to produce Schiff bases, one of the most popular classes of compounds in both organic and coordination chemistry. In certain cases, however, compounds other than Schiff bases have been reported to result from such reactions. After conducting a representative reaction… (More)
Nanojars are emerging as a class of anion sequestration agents of unparalleled efficiency. Dinegative oxoanions (e.g., carbonate, sulfate) template the formation of a series of homologous nanojars [Cu(OH)(pyrazolato)]n (n=27-31). Pyridine selectively transforms less stable, larger CO3(2-) nanojars (n=30, 31) into more stable, smaller ones (n=27, 29), but… (More)
The reaction of CuSO4·5H2O, 4-chloro-pyrazole (4-Cl-pzH) and tri-ethyl-amine (Et3N) in di-methyl-formamide (DMF) produced crystals of di-aqua-hexa-kis-(μ-4-chloro-pyrazolato-κ(2) N:N')bis-(N,N-di-methyl-formamide)di-μ3-hydroxido-bis-(μ4-sulfato-κ(4) O:O':O'':O'')hexa-copper(II) N,N-di-methyl-formamide tetra-solvate dihydrate,… (More)
Unprecedentedly strong binding of HXO4(2-) and XO4(3-) ions (X = P or As) within self-assembled nanohosts with protein-like anion binding cavities is reported. One of the nanohosts binds two XO4(3-) ions at an unusually short distance, resulting in helical chirality.
Dimeric Ln(3+)[15-metallacrown-5] compartments selectively recognize carboxylates through guest binding to host metal ions and intermolecular interactions with the phenyl side chains. A systematic study is presented on how the size, selectivity, and number of encapsulated guests in the dimeric containers is influenced by the… (More)
