Reaction of the secondary amine group of 3,11-dibenzyl-3,7,11,17-tetraazabicycloheptadeca-1(17),13,15-triene (L2) with 2-chloromethylpyridine in the presence of base, or with 1-(hydroxymethyl)pyrazole, gives two new pendant-arm macrocycles, L3 and L4, having 7-(2'-pyridylmethyl) and 7-(1'-pyrazolylmethyl) groups, respectively.Complexes of Co(2+), Ni(2+), Cu(2+), and Zn(2+) with L3 and L4 have been isolated and characterised.The structure of 3)>3 and L4 show the presence of only a single symmetric isomer in each case.In the 4)(dmso)>(2+) ion, the presence of a strongly coordinated dimethyl sulphoxide (dmso) molecule is confirmed both in the solid state and in solution, and solid comlexes of formula 2 (L = L3 or L4; M = Co, Ni, or Cu) have been prepared in all cases

A new route is described for the synthesis of tetra-azamacrocycles functionalised with a pendant-arm which can co-ordinate to a centrally placed metal ion; the first example of macrocycle with a pendant pyridyl group is reported.
