Two new Schiff base complexes; synthesis, characterization, NMR, IR and mass study of a number of [1+1] Cd(II) complexes
Journal Title: Iranian Chemical Communication - Year 2018, Vol 6, Issue 1
Abstract
In this paper we report the synthesis and characterization of two new binuclear Cd(II) macrocyclic Schiff base complexes [CdL23pydfp(NO3)], (1), and [CdL33pydfp(NO3)], (2). [1+1] cyclocondensation of L23py = N-(2-pyridylmethyl)-N-(3-aminpropyl)-1,3-diaminoethane and L33py = N-(3-pyridylmethyl)-N-(3-aminpropyl)-1,3-diaminopropane and 2,6-diformyl-4-methylphenol, dfp, in the presence of Cd(NO3)2.4H2O in equimolar ratios gave two new macrocylclic complexes. Resulting complexes were characterized by NMR, IR, mass spectroscopy and elemental analysis. Spectroscopy studying results show in spite the nitrogen and oxygen atoms of macrocyclic ligand with N4O donor set, one nitrate molecule (with two donor oxygen atoms) is coordinated to the Cd(II) center in each complex. So, the cadmium center is seven coordinated.
