  Synthesis and co-ordination chemistry of the pyridyl pendant-arm azamacrocycles 1-(2-pyridylmethyl)-1,5,9-triazacyclododecane L¹and 1-(2-pyridyl-2′-ethyl)-1,5,9-triazacyclododecane L², with nickel (II), copper(II) and zinc(II). Crystal structures of [Ni(L¹)(O₂NO)]NO₃and [ZnL²][Zn(NO₃)_3.67Cl_0.33]

  摘要：

  The azamacrocyclic ligands 1-(2-pyridylmethyl)-1,5,9-triazacyclodod L(1) and 1-(2-pyridyl-2'-ethyl)-1,5,9-triazacyclododecane L(2) have been prepared, and their complexes with hydrated nickel(II). copper(ir) and zinc(II) nitrates have been isolated. The nickel(II) complexes are high spin and six-co ordinate, whilst C-13 NMR spectroscopy shows that [ZnL(1)(OH2)](2+) exists as a symmetric trigonal-bipyramidal isomer in solution, and [ZnL(2)](2+) exists as a 2:1 mixture of tetrahedral and asymmetric trigonal-bipyramidal isomers. X-Ray crystallography has been used to determine the solid-state structures of the octahedral [NiL(1)(O2NO)](+), and the tetrahedral isomer of [ZnL(2)](2+).
