Cr(Ⅲ) Complexes of Tetraazamacrocycles Derived from α-Diketones and Diaminoalkanes
Pramod K. Rai*, Ajay K. Gupta, Raghu N. Prasad
Template condensation of α-diketones such as 2,3-butanedione or benzil with diaminoalkanes such as 1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane, 1,6-diaminohexane, 1,8-diaminooctane or 1,12-diaminododecane in the presence of Cr(Ⅲ) results in the formation of complexes of the type [CrLX2]X (where L = tetraazamacrocycle having 12 to 32-membered ring and X = NO3-or Cl-). The complexes have been characterized by elemental analyses, magnetic measurements and IR and diffuse reflectance spectra.
