Os3(/i-H)( -HNNNH)(CO),o, obtained from Me3SiN3 and Os3H2(CO)io after heating under reflux in hexane for 24 hours, has been shown to possess a triazenide-bridged structure (Fig. 9) (113). Corresponding reactions using alkyl or aryl azides RN3 (R = Bu", Cy, Ph, Bz, or C Ph =CH2) afford mono-substituted triazenide derivatives Os3(/i-H)(/i-HNNNRXCO)io. one of which (R = Ph) has been shown to possess a similar structure (14) (26,43). 

Rh(ArNNNAr)(CO)(PPh3)]2 (19a/b) and [Rh(ArNNNAr)(diene)] (20), respectively 42). Ambiguous molecular weight and mass spectroscopic data fail to distinguish between n values of 1 and 2 for [Rh(ArNNNAr)(diene)] , but NMR spectra favor the triazenide-bridged binuclear structure shown. The blue-black products obtained by treatment of [Rh(ArNNNAr)(CO)2]2 with cycloheptatriene were tentatively assigned structure 21 42). Cycloocta-...
