Synthesis and Crystal Structure of {6-Amino-5-[6-amino-4-oxo-(1H)-pyrimidin-2-yl]thio-2-thioxo-pyrimidin-4-onato}[tris(2-aminoethyl)amine]cobalt(III) Perchlorate

The novel tris(2-aminoethyl)aminecobalt(III) complex containing a dimerized ligand Hatuc-atuc (6-amino-5-[6-amino-4-oxo-(1H)-pyrimidin-2-yl]thio-2-thioxo-pyrimidin-4-onate(2-)) was prepared. The crystal structure revealed that Hatuc-atuc coordinates through the S/N donors and exhibits the intermolecular π–π stacking and the double N–H···O hydrogen bond interactions.
