In the title compound, [CuBr(2)(H(2)O)(2)]·C(12)H(24)O(6)·2H(2)O, the Cu(II) atom, which is situated on an inversion centre and has a slightly distorted square-planar geometry, and the two coordinated water mol-ecules are linked to the 18-crown-6 macrocycles by O-H⋯O hydrogen bonds. The water mol-ecule of crystallization further links the metal complex and the crown ether macrocycles into a cha...

o-Phthalonitrile couples with chelating dioxime on nickel(II), with formation of a dinuclear nickel(II) macrocyclic complex--the first representative of a new class of imine-appended macrocycles.

Multiple synthetic pathways were explored for the preparation of ethynylarene-containing ferrocenylene macrocyles. Accordingly, synthesis novel bis- and tris-ferrocenylene macrocycles, containing a diethynylpyridine bridging group was achieved, evidence is also provided number linear-analogues formed as by-products. The electrochemical properties macrocycles examined, it shown that observable r...

A rare class of mixed-metal [2]catenane has been assembled via magic ring synthesis of dinuclear copper(II) and gold(III) dithiocarbamate macrocycles.

Self-assembly reactions between di- and tritopic gold(i) metallaligands bearing terminal pyridine rings Pd(ii) or Pt(ii) fragments produce heterometallic macrocycles cages with cavities of different sizes shapes.

Pyridazine-templated dicobalt macrocycles reversibly support five oxidation states with unusually positive Co(II)/Co(I) redox couples, and are also active proton reduction electrocatalysts.

Coordination self-assembly of a series of tetranuclear Pt(II) macrocycles containing an organometallic backbone incorporating ethynyl functionality is presented. The 1:1 combination of a linear acceptor 1,4-bis[trans-Pt(PEt3)2(NO3)(ethynyl)]benzene (1) with three different dipyridyl donor ‘clips’ (La–Lc) afforded three [2 + 2] self-assembled Pt(II)4 macrocycles (2a–2c) in quantitative yields, r...

Non-coordinated hydroxymethylphosphines react readily with primary and secondary amines by the phosphorus Mannich reaction. To determine if this reactivity can be used to synthesize phosphine macrocycles, trans-Fe(DHMPE)(2)Cl(2) (DHMPE = 1,2-bis(dihydroxymethylphosphino)ethane) was prepared and reacted with various amines. However, no phosphorus Mannich reactivity was observed. In order to unde...

our main objective is a better understanding of spin spin interaction of dinuclear copper(ii) complexes through  system. the synthesis and characterization of two new dinuclear copper(ii) complexes, based on the use of large, pyrole-containing macrocycles, the so called “ expanded porphyrins” , [cu2(macrocycle)]4+ is described. a chloroform solution spectrum of two complexes taken at room tem...
