Abstract

The radical initiated reactions of $Ru_{3}(CO)_{12}$ with pyrazolyl substituted diphosphazanes $Ph_{2}PN(R)PPh(N_{2}C_{3}HMe_{2}-3,5)$ $[R = (S)-^*CHMePh(1) or CHMe_{2}(2)]$ proceed via P-N(pyrazole) bond rupture resulting in the formation of phosphido clusters, $[Ru_{3}(CO)_{5}(\mu_{sb}-CO)_{2}(\mu_{3}-N,N'-\eta^{1}:\eta^{1}:\eta^{1}-N_{2}C_{3}HMe_{2}-3,5)$ ${\mu-P,P'-Ph_{2}PN(R)PPh}] [R=(S)-^*CHMePh(3) or CHMe_{2}(4)]$. The pyrazolate moiety adopts an unusual triply bridging $\mu_{3}-\eta^{1}:\eta^{1}:\eta^{1}$-mode of coordination in these clusters.
