Complexes of polyaza macrocycles bearing pendent coordinating groups

Two solvatomorphic forms of a copper complex formulated as Cu(L1)(ClO4)2·1.2H2O and Cu(L1)(ClO4)2, whereL1is 3,10-C-meso-3,5,7,7,10,12,14,14-octamethyl-1,4,8,11-tetraazacyclotetradecane

“…Synthetic macrocyclic complexes are important in view of their presence in many biologically significant and naturally occurring metal complexes, such as vitamin B12, haemoglobin and chlorophyll, all of which play vital roles in biological systems (Bernhardt & Lawrance, 1990;Reid & Schroder, 1990). Saturated tetraaza macrocycles have proven to be versatile macrocyclic ligands capable of forming stable inert complexes with a variety of biomedically important metal ions, the chemistry of which has attracted interest due to their involvement in a variety of catalytic, biochemical and industrial processes (Kimura et al, 1992(Kimura et al, , 1994.…”

The synthesis, crystal structures and antimicrobial studies of C‐methyl‐substituted hexaaza macrocycle of Cu(II) having aromatic pendant arm

“…[1,2] Metal-directed condensation reactions involving coordinated polyamines and formaldehyde have been utilized for the preparation of various types of polyaza macrocyclic complexes. Metal template syntheses often provide selective routes toward products that are not obtainable in the absence of metal ions.…”

Crystal and solution structure of a pendant-armed macrocyclic complex of palladium(II)

“…There has been considerable recent interest in the chemistry of metal complexes involving macrocyclic ligands with pendant arms (1). In some instances this derives from biological studies where it has been demonstrated that the complexation of functional groups that are integral parts of the structure but not fixed rigidly in place, provides a mechanism for activation of the metal site (2,3).…”
