Compounds containing ruthenium(IV) such as the dithiocarbamates Ru(S2CNR2)3C1 (section 1.8.6) and the porphyrin complexes (section 1.8.6) were mentioned above. Certain phosphine complexes RuH4(PR3)3 are best regarded as ruthenium(II) compounds Ru(H)2(t 2-H2)(PR3)3 (section 1.8.2).

A number of bis(dithiocarbamate) ruthenium(II) complexes have been reported. Heating thiuram disulfides with [Ru3(CO)i2] in heptane yields cis-[Ru(CO)2(S2CNR2)2] (R = Me, Et) (169, 1359). Other routes have also been reported to these cis dicarbonyl complexes. For example, addition of 2 equiv of dithiocarbamate salt to [Ru2(CO)4(MeCN)g][BF4]2, [Ru2(C0)4(p-02CMe)2(-MeCN)2] (1360), or [Ru(CO)2Cl2] (169), while an earlier preparation involves addition of NaS2CNMe2 to cw-[RuCl2(CO)2(PPh3)2] (1361).
