Copper(II) complexes with 2,3,4-trimethoxybenzoic acid (H234-tmbz) and 2,4,6-trimethoxybenzoic (H246-tmbz), [Cu2(234-tmbz)4(H2O)2] (6) [Cu(246-tmbz)2(µ-H2O)2(H2O)2]n (7), were synthesized characterized by elemental analysis, infrared UV-vis spectra temperature dependence of magnetic susceptibilities (1.9–300 K). The X-ray crystal structures revealed that the former 6 is a dinuclear cluster havi...

The chiral macrocyclic amines R-L and S-L derived from the 3 + 3 condensation of 2,6-diformylpyridine and (1R,2R)-1,2-diaminocyclohexane or (1S,2S)-1,2-diaminocyclohexane form enantiopure trinuclear Ni(ii) and Cu(ii) complexes [Ni3(L)(H2O)2Cl5]Cl and [Cu3(L)Cl4]Cl2 and form the dinuclear complex [Zn2(L)Cl2](ZnCl4) with Zn(ii). The X-ray crystal structures of these complexes indicate remarkably ...

The reaction of copper(II) chloride and zinc(II) chloride with N-(2-methylphenyl)-3-(1'-salicylaldehydene-2'-imine-ethane)-butanamide(H2L2a) or (MPSB), N-(2-methylphenyl)-3-(1'-(3'-methoxysalicylaldehydene-2'-imine-ethane)-butanamide (H2L2b) or (MPMSB) and N-(2-methylphenyl)-3-(1'-(2'-hydroxyacetylene-2'-imine-ethane)-butanamide (H2L2c) (MPHB) leads to the formation of a series of new complexes...

A novel tripodal ligand with three different arms, viz., pyridine, phenol and an oxime and its copper(II) complex were synthesised. The X-ray crystal structure of the compound reveals that it is a dinuclear complex consisting of two copper(II) ions doubly bridged by two oximato groups in a trans arrangement. The complex contains unusual cis-axially coordinated phenolates as well as a novel inte...

A large library of Cu(II) complexes with mononucleating and dinucleating ligands was synthesized to investigate their potential as catalysts for the catalytic oxidation of 3,5-di-tert-butylcatechol (3,5-DTBC). X-ray structure determination for a number of these complexes revealed relatively large Cu···Cu distances and the formation of polymeric species. Comparison of the 3,5-DTBC oxidation rate...

The Cover Feature shows that 1-butene molecules can penetrate into a dense crystalline solid and drive the transformation of planar trinuclear fluorinated copper(I) pyrazolate complexes toward boat-shaped, dinuclear copper-butene adducts. chemistry these with is also examined in solution, comparison analogous adducts formed ethene propene provided.
