Syntheses of Square-planar Nickel-(II) and -(I) Complexes of an Octaaza Macrohexacyclic Ligand and Crystal Structure of the Nickel(II) Complex

The square-planar nickel(II) complex of the octaaza macrohexacyclic ligand 1,3,6,8,10,12,15,17-octaazahexacyclo<15.6.1.1 3,17 .1 6,0 .1 8,12 .0 18,23 >heptacosane, 2, has been synthesized by template condensation of the nickel(II) complex of 3,7-bis(2-aminoethyl)-1,3,5,7-tetraazabicyclo<3.3.1>nonane with formaldehyde and trans-cyclohexane-1,2-diamine.The complex exhibits an unusually strong ligand-field strength compared with other square-planar nickel(II) complexes of 14-membered azamacrocycles.Cyclic voltammetry indicated a one-electron reduction potential at -1.32 V vs.Ag-AgCl and no oxidation peak up to +1.59 V.The complex crystallizes in the orthorhombic space group Pna2 1 , with a = 17.934(2), b = 16.056(3), c = 9.612(1) Angstroem and Z = 4.The structure was solved by the heavy-atom method and refined by full-matrix least squares to a final R = 0.0447 for 2092 observed 2?(I)> reflections.The ligand contains bicyclononane and tricyclotetradecane cage ring moieties fused at both ends of two ethylenediamine groups.The average Ni-N distance is 1.904(7) Angstroem.The N-N bite distances are 2.706(6) and 2.698(6) Angstroem for the five-membered chelate rings and 2.703(6) and 2.665(6) Angstroem for the six-membered chelate rings so that the cavity size of the ligand is similar to that of 1,4,7,10-tetraazacyclododecane.Reduction of 2 with Na/Hg gave PF6, which shows an anisotropic axial EPR powder spectrum with g values of g <*> > g <*> .
