In this work were synthezised two squaraines, named sodium 1,2bis(dicyanomethylene) squarate (CDCMSQ) and sodium 1,3- bis(dicyanomethylene)squarate (TDCMSQ)], both derived from squaric acid (1,2-dihydroxy-3,4-cyclobutene), as well as eight new coordination compounds with each squaraine involving the transition metal ions Mn2+, Zn2+, Ni2+ and Co2+. The ligands were submitted to 13C nuclear magnetic resonance, whereas the ligands and all coordination compounds were submitted to vibrational spectroscopic analysis (infrared and Raman), thermogravimmetry, powder X-ray diffraction and electronic spectroscopy. The 13C RMN data for the ligands have shown a more delocalized electronic structure for TDCMSQ when compared to CDCMSQ, by comparing the c...
