| Abstract: | Interaction of [Ru(NO)Cl3(PPh3)2] with K[N(R2PS)2] in refluxing N,N-dimethylformamide afforded trans-[Ru(NO)Cl{N(R2PS)2}2] (R = Ph (1), Pri (2)). Reaction of [Ru(NO)Cl3(PPh3)2] with K[N(Ph2PSe)2] led to formation of a mixture of trans-[Ru(NO)Cl{N(Ph2PSe)2}2] (3) and trans-[Ru(NO)Cl{N(Ph2PSe)2}{Ph2P(Se)NPPh2}] (4). Reaction of Ru(NO)Cl3 · xH2O with K[N(Ph2PO)2] afforded cis-[Ru(NO)(Cl){N(Ph2PO)2}2] (5). Treatment of [Rh(NO)Cl2(PPh3)2] with K[N(R2PQ)2] gave Rh(NO){N(R2PQ)2}2] (R = Ph, Q = S (6) or Se (7); R = Pri, Q = S (8) or Se (9)). Protonation of 8 with HBF4 led to formation of trans-[Rh(NO)Cl{HN(Pri2PS)2}2][BF4]2 (10). X-ray diffraction studies revealed that the nitrosyl ligands in 2 and 4 are linear, whereas that in 9 is bent with the Rh–N–O bond angle of 125.7(3)°. |
