Bis(imino)pyridines : Surprisingly reactive ligands and a gateway to new families of catalysts

A magneto-structural relationship showing linear dependence of antiferromagnetic exchange coupling constant (–J) on Ni–O–Ni bridge angle as well as the intramolecular Ni ⋯ Ni distance has been obtained with a series of phenoxy-bridged macrocyclic dinickel(II) complexes with centrosymmetric structures.

Variable-temperature (5-300 K) susceptibility measurements carried out for the binuclear nickel(II) complexes of a tetraamino diphenol macrocyclic ligand (H 2 L) of compositions [Ni 2 L(H 2 O) 4 ] (ClO 4 ) 2 .4NH 2 CONH 2 (1),[Ni 2 L(NCS) 2 (H 2 O) 2 ]-2Me 2 NCHO (2), [Ni 2 L(MeOH) 2 (ClO 4 ) 2 ].2NHEt 3 ClO 4 (3), [Ni 2 L(im) 2 ] (ClO 4 ) 2 (4), [Ni 2 L(py) 2 ] (ClOg) 2 (5), and [Ni 2 L(μ-O 2 CCH 2 NH 3 )(H 2 O) 2 ] (ClO 4 ) 2 .2H 2 O (6) are reported

Magneto-structural correlations in macrocyclic dinickel(II) complexes : tuning of spin exchange by varying stereochemistry and auxiliary ligands

The reaction equilibria [H4L]2+ + Zn(OAc)2 ⇌ [Zn(H2L)]2+ + 2HOAc (K1) and [Zn(H2L)]2+ + Zn(OAc)2 ⇌ [Zn2L]2+ + 2HOAc (K2), involving zinc acetate and the perchlorate salts of the tetraiminodiphenol macrocycles [H4L1-3](ClO4)2, the lateral (CH2)n chains of which vary between n = 2 and n = 4, have been studied by spectrophotometric and spectrofluorimetric titrations in acetonitrile. The photoluminescence behavior of the complexes [Zn2L1](ClO4)2, [Zn2L2(H2O)2](ClO4)2, [Zn2L2(μ-O2CR)](ClO4) (R = CH3, C6H5, p-CH3C6H4, p-OCH3C6H4, p-ClC6H4, p-NO2C6H4), and [Zn2L3(μ-OAc)](ClO4) have been investigated. The X-ray crystal structures of the complexes [Zn2L2(H2O)2](ClO4)2, [Zn2L3(μ-OAc)](ClO4), and [Zn2L2(μ-OBz)(OBz)(H3O)](ClO4) have been determined. The complex [Zn2L2(μ-OBz)(OBz)(H3O)](ClO4) in which the coordinated water molecule is present as the hydronium ion (H3O+) on deprotonation gives rise to the neutral dibenzoate-bridged compound [Zn2L2(μ-OBz)2]·H2O. The equilibrium constants (K) for the reaction [Zn2L2(H2O)...
