Ruthenium(III) has been precipitated gravimetrically in the pH range 7.0‐8.5 with morpholine‐4‐carbodithioate and determined by weighing as a black complex (C 5 H 6 ONS 2 ) 3 Ru after drying at l00–110°C. The interference of the various metal ions has been avoided by using an ammonical mixture of EDTA and tartrate (1:1 molar ratio). The complex is thermally stable up to l60°C.
