The compositions of different compounds of 99Tc(IV) and hydroxy-ethylidendiphosphonic acid have been evaluated using spectrophotometrical and potentiometric methods. The ligand reacts with K2TcBr6 as well as with TcO4′ and SnCl2 under formation of Tc(OH)3LH3, Tc(OH)3LH2−, TcOOHLH2−, Tc2(OH)4LH33+ Tc2(OH)6LH2, Tc2(OH)8L4− and Tc(OH)x(LHy)2(4-x+8+2y)+ complexes respectively. In account of the minor technetium concentrations in 99mTc-radiopharmaceuticals for skeletal imaging the last mentioned compound may be the major component in such preparations.
