摘要：

Anew series of dichloro/dinitrato (2,6,9,13,1 8-pentaazacbicyclo [12.3.1]octadeca- 1(18),14,16-triene) metal (11) [MLX,] (M = Mn(II), Co(II), Ni(II) and Zn(II); X = Cl or NO3) and (2,6,9,13,18-pentaazacyclo[ 12.3. 1]octadeca-1(18),14,16-triene) copper(II) dichloride/dinitrate [CuL]X-2 (X = Cl or NO3) have been synthesized by the template condensation reaction of 2,6-diaminopyridine with 1,2-diaminoethane and 1,3-dibromopropane. The complexes were studied by elemental analysis, magnetic susceptibility and conductivity measurements. Various spectroscopic techniques, viz. IR, H-1-NMR, EPR, UV/Vis, were used to establish their structures. Except for the complexes of copper(II), which are square planar, all other complexes have octahedral structures.
