“…It is well known that the chemical properties and structure of the partially or fully N-functionalized macrocyclic compounds are distinctly different from those of the unsubstituted ones [1,2]. An investigation of metal complexation studies across a range of related ligands has provided a useful background on which to base further ligand design.…”

A novel tetradentate nitrogen donor [N 4 ] macrocyclic ligand, i.e. 3,5,13,15,21,22-hexaaza-2,6,12,16-tetramethyl-4,14-dithia-tricyclo[15.3.1.1(7-11)]docosane-1(21), 2,5,7,9,11(22),12,15,17,19-decaene, has been synthesized. Mn(II), Co(II), Ni(II) and Cu(II) complexes with this ligand have been prepared and subjected to elemental analyses, molar conductance measurements, magnetic susceptibility measurements, mass, 1 H-n.m.r. (Ligand), i.r., electronic, and e.p.r. spectral studies. On the basis of molar conductance the complexes may be formulated as [M(L)X 2 ] and [Ni(L)]X 2 [where M = Mn(II), Co(II) and Cu(II), and X = Cl ) and NO À 3 ] due to their nonelectrolytic nature in dimethylsulphoxide (DMSO). All the complexes are of the high spin type and are six coordinated. On the basis of i.r., electronic and e.p.r. spectral studies an octahedral geometry has been assigned to Mn(II) and Co(II), square planar for Ni(II) complexes, and tetragonal for Cu(II) complexes. The antimicrobial activities of the ligand and its complexes, as growth inhibiting agents, have been screened in vitro against several species of bacteria and plant pathogenic fungi.

“…1 Synthetic macrocycles are a growing class of compounds with varying chemistry, a wide range of different molecular topologies and sets of donor atoms. [2][3][4][5][6] The chemical properties of macrocyclic complexes can be tuned to force metal ions to adopt unusual coordination geometry. Currently a great deal of attention is being focussed on macrocyclic ligands because they play an important role in many aspects of chemistry, medicine and the chemical industry.…”

A poly (vinyl chloride)-based membrane of 2,9-dihydroxy-1,10-diphenoxy-4,7-dithiadecane (C 20 H 26 O 4 S 2) as a neutral carrier was prepared and investigated as an Y 3+-selective electrode. Effects of various plasticizers and anion excluders were studied in detail and improved performance was observed. The best performance was obtained for the membrane sensor having a composition of L: PVC: NPOE: PA in the ratio of 2:30:62:6 (mg). The performance of the membrane was found to be the following: A Nernstian slope of 20.0 ± 0.2 mV per decade across a broad range (1.0 × 10 −9 to 1.0 × 10 −1 mol dm-3); a detection limit of 2.14 × 10-10 mol dm-3 between the pH = 4.5 and 9.0; additionally, the response time was about 15 s; good Y 3+ selectivity over a wide variety of other metal ions. The membrane sensor was applied as an indicator electrode in potentiometric titration of fluoride ion and also used for determination of F − ion in tap water and toothpaste samples.

“…The formation of macrocyclic complexes depends significantly on the dimension of the internal cavity, on the rigidity of the macrocycles, on the nature of its donor atoms and on the complexing properties of the anion involved in the coordination [4,6]. Synthetic macrocycles are a growing class of compounds with varying chemistry a wide range of different molecular topologies and sets of donor atoms [7][8][9][10][11][12][13]. In recent years, polyaza macrocyclic ligands with rigid structure units have played important roles in transition metal complexes.…”

Six new macrocyclic complexes were synthesized by reaction of 1,4-bis(2-carboxyaldehyde phenoxy)butane with various diamines. Then, their nickel(II) perchlorate complexes were synthesized by the template effect by reaction of 1,4-bis(2-carboxyaldehyde phenoxy)butane, Ni(ClO 4 ) 2 AE 6H 2 O and various diamines. The metal-to-ligand ratio of Ni II metal complexes was found to be 1:1. The compounds are coordinated to the central metal as tetradentate O 2 N 2 ligands The Ni II complexes are proposed to exhibit tetrahedral geometry. Ni II metal complexes are 1:2 electrolytes as shown by their molar conductivities (K M ) in DMF (dimethyl formamide) at 10 )3 M. The structure of Ni II metal complexes is proposed from elemental analysis, f.t.-i.r., u.v.-vis., magnetic susceptibility measurements, molar conductivity measurements and mass spectra.
