Isolation and characterization of a polymeric lanthanum citrate
The first lanthanide citrate coordination polymer with the formula [La(Hcit)(H2O)]n (Hcit3- = C(OH)(COO -)(CH2COO-)2) was prepared from La2O3 and citric acid at pH = 2.2-2.5 under hydrothermal conditions at 120 °C. The compound was characterized by elemental analysis, IR, TG-DTA, and X-ray crystallo...
