Kompleks Praseodimium Ditiokarbamat 1,10 Fenantrolin

Seven promethium (Pr) complexes with 1,10-phenantroline were successfully synthesized using in situ methods from the reactions of eight amines with praseodymium(III) salts together with carbon disulphide. Methatesis and condensation were the most successful methods to prepare praseodymium dithiocarb...
