SYNTHESIS, CRYSTAL STRUCTURE, AND THERMAL DECOMPOSITION KINETICS OF HOLMIUM WITH BENZOATE AND 2, 2'-BIPYRIDINE COMPLEX

The complex [Ho(BA)3bipy]2 (BA=benzoate; bipy=2,2'-bipyridine) was synthesized and characterized by elemental analysis, infrared spectra, ultraviolet spectra, single-crystal X-ray diffraction, thermogravimetry and differential thermogravimetry (TG-DTG) techniques. The crystal is monoclinic with...
