%X This article outlines the reactions of the well known [RuCl(¦Ç6-p-cymene)]2(¦Ì-¦Ç4-C2O4) and [RuCl(¦Ç6-p-cymene)(¦Ç2-dppm)][PF6] ruthenium complexes with C2O4(Me4N)2 in the mol ratios 1:1 and 2:1. While the 2:1 ratio reaction led to the sole and expected binuclear product {[Ru(¦Ç6-p-cymene)(¦Ç2-dppm)]2(¦Ì-¦Ç2-C2O4)}[PF6]2, the reaction also afforded the unexpected mononuclear complex [RuCl(¦Ç2-C2O4)(¦Ç6-p-cymene)][Me4N]. This can also be obtained in improved yield by reacting [RuCl2(p-cymene)]2 with C2O4[Me4N]2 in a 1:1 mol ratio. Surprisingly, when [RuCl(¦Ç6-p-cymene)]2(¦Ì-¦Ç4-C2O4) was reacted with an equimolar amount of the ligand dppm, the expected complex {[Ru(¦Ç6-p-cymene)]2(¦Ì-¦Ç4-C2O4)(¦Ì-dppm)}[PF6]2 was accompanied by [RuCl(¦Ç6-p-cymene)(¦Ç2-dppm)][PF6] in an inseparable solid mixture.
