    Author: Rathi P, Sharma K, Singh DP.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2014 Sep 15; 130():72-5. PubMed ID: 24769359.
    Abstract:
    Macrocyclic complexes of the type [MLX]X2; where L is (C30H28N4), a macrocyclic ligand, M=Cr(III) and Fe(III) and X=Cl-, CH3COO- or NO3-, have been synthesized by template condensation reaction of 1,8-diaminonaphthalene and acetylacetone in the presence of trivalent metal salts in a methanolic medium. The complexes have been formulated as [MLX]X2 due to 1:2 electrolytic nature of these complexes. The complexes have been characterized with the help of elemental analyses, molar conductance measurements, magnetic susceptibility measurements, electronic, infrared, far infrared, Mass spectral studies and molecular modelling. Molecular weight of these complexes indicates their monomeric nature. On the basis of all these studies, a five coordinated square pyramidal geometry has been proposed for all these complexes. These metal complexes have also been screened for their in vitro antimicrobial activities.
