The complex [CdIIL2(NO2)2] (L= 4-aminoantipyrine) was synthesized and the structural aspects of the complex were determined from elemental analysis, EC measurement, IR, NMR spectra and single crystal X-ray diffraction analysis. The spectral and X-ray diffraction studies of the complex indicate that the crystal system is monoclinic with the P2/n space group. The cadmium ion in this compound is eight coordinated with two bidentate nitrite groups and two bidentate 4-aminoantipyrine ligands with extended coordination. The nitrite ions and 4-aminoantipyrine molecules are bidentated to the metal ion and form four member chelate rings. The geometry of the complex is distorted dodecahedron.
