The binding modes of 2-((2-aminoethyl)amino)ethanol-based ligands were explored using the Cambridge Structural Database (CSD). To extend this field, a new cadmium complex containing 2-((2-aminoethyl)amino)ethanol (AEAE), [Cd(AEAE)2][Cd(AEAE)2]′[CdI4]2 (1), was prepared and characterized by spectroscopic methods and single-crystal X-ray diffraction. The reaction of AEAE with a 1:1 mixture of CdI2 and HgI2 was also investigated. The complex, [Cd(AEAE)2][I2Hg(μ-I2)2HgI2] (2), was synthesized and

Geometrical investigation for complexes containing Cd(Namine2Oalcohol)2, CdIn, and HgIn environment were carried out using the CSD software. Also different possible diastereomers which can be formed in coordination of a pair of tridentate AEAE ligands in octahedral geometry were studied and discussed.
