It is shown that the first step in the thermal decomposition of europium(III) oxalate leads to reduction to the divalent state. In an oxidizing atmosphere the europium is reoxidized and continues decomposing gradually to Eu/ sub 2/O/sub 3/ at 390 deg . In an atmosphere of CO/sub 2/, Eu(II)Ox is stabilized at 320 deg . In vacuum, Eu(II)CO/sub 3/ admixed with carbon (originating in disproportionation of CO) is obtained in the temperature range 360--420 deg . A unified mechanism for the decomposition of oxalates is proposed, in which a trace of carbon monoxide acts as catalytic agent in the reductive decomposition of oxalates of reducible metal ions.
